A numerical approach to predict the elastic properties of composite materials departing from the properties of the individual constituents is presented. Using a recently proposed algorithm which generates a random distribution of fibres emulating the real distribution in the transverse cross-section of composite materials, an estimate of the elastic properties is obtained by performing volumetric homogenisation of the results from micromechanical analyses. The influence of different geometrical parameters used in the generation of the random distribution of fibres is analysed, namely, the dimensions of the representative volume element, the fibre radius, and the interval between neighbouring fibres.

Hajikazemi, M. Mehdikhani, M. N. Mavrogordato, P. P. Camanho, R. Tavares, S. M. Spearing, S. Lomov, S. Pimenta, W. Van Paepegem, Y. Swolfs

Summary: This study experimentally validated blind predictions of six state-of-the-art models on the longitudinal tensile failure of unidirectional fibre-reinforced composites. It was found that models without major conservative assumptions regarding stress redistributions around fibre breaks tend to overestimate failure strains and strengths, while models with at least one such assumption showed better agreement for these properties. The study also revealed that all models failed to accurately predict the development of fibre break (and cluster).

An invariant-based elasto-visco-plastic model for unidirectional polymer composites at finite strains

Igor A. Rodrigues Lopes, Pedro P. Camanho, Francisco M. Andrade Pires, Albertino Arteiro

Summary: An invariant-based constitutive model for unidirectional composites, including viscous effects in the elastic and plastic regimes at finite strains, is proposed. The model utilizes a multiplicative decomposition of the deformation gradient and an isoclinic configuration to avoid intermediate configuration non-uniqueness. It incorporates visco-elastic behavior through the generalised Maxwell model, with a transversely isotropic yield function and a non-associative plastic potential. Visco-plastic effects are introduced through the Perzyna overstress function. The performance of two algorithms for implicit integration is compared, with the semi-implicit stress update algorithm being faster and the fully implicit stress update algorithm guaranteeing quadratic convergence rate in the Newton-Raphson scheme. The model accurately predicts stress-strain responses for different fiber orientation angles and captures fiber re-orientation due to external loading.

Summary: This paper presents the development and validation of a mesoscale numerical model to predict the bearing failure of composite laminates reinforced by unidirectional continuous fibers, focusing on specimens that show a significant non-linear response prior to failure. Thorough analyses and comparisons of the experimental and numerical results show a good correlation of the bearing strengths and overall deformation, as well as good agreement in terms of damage size and damage shape. Relevant limitations include difficulties in predicting the post-peak plateau stresses and the loading displacements in some configurations, setting the stage for additional future research.

Summary: This paper demonstrates the capability of mesh superposition based finite element models to predict the nonlinearity of composite stress-strain response under tensile and shear loading, induced by damage and matrix plasticity. A consistent elasto-plastic damage model is implemented for matrix damage simulation, while Puck's damage criterion and a continuous damage mechanics model are used for simulating intra-yarn damage initiation and propagation. The numerical simulations are validated by comparing with experimental results of a glass/epoxy laminate under tension and shear loading.

Modeling fracture of multidirectional thin-ply laminates using an anisotropic phase field formulation at the macro-scale

Anatoli Mitrou, Albertino Arteiro, Jose Reinoso, Pedro P. Camanho

Summary: In this study, an equivalent single layer approach using the Phase Field method is developed to model fracture events in multidirectional balanced thin-ply laminates. The anisotropic nature of the laminates is accounted for by introducing a structural tensor based on scaled directional vectors. The scaling constants are defined using the laminate lay-up and intra-laminar fracture toughness, reducing the number of input parameters and providing a new perspective on their definition. The proposed formulation is implemented using an anisotropic conductivity matrix in Abaqus, simplifying the simulations. Experimental results are successfully reproduced, validating the model for size effects and off-axis loading responses.

Summary: In this work, a bio-inspired microstructural concept is designed and manufactured to enhance the longitudinal compressive performance of multidirectional carbon fiber reinforced polymer (CFRP) laminates. Taking inspiration from layered materials found in nature, such as the anchoring spicula of the deep-sea glass sponge Monoraphis chuni, the authors created various design concepts and developed a strategy to reproduce the characteristic alternation of stiff and soft regions observed in the natural material. The proposed microstructure showed significant improvements in failure load and ligament specific stress at failure compared to a baseline laminate, suggesting its potential for lightweight structure design subjected to compression loading.

A novel profiling concept leading to a significant increase in the mechanical performance of metal to composite adhesive joints

Adam D. Whitehouse, Victor Medeau, Lorenzo Mencattelli, Bamber Blackman, Silvestre T. Pinho

Summary: This study develops a novel profiling concept to improve the mechanical performance of adhesive joints between metallic adherends and composite substrates. The experiments show that profiling the edge of the metallic adherend can increase the peak load by at least 27% and improve the stability of failure. Further experiments demonstrate that increasing the profile parameters can achieve significant mechanical performance gains. Acoustic emission monitoring data shows that profiling results in failure initiation occurring at higher loads, suggesting better stress distributions and lower peak stresses. Fracture surface analysis reveals that profiling deflects the translaminar fracture path and enhances damage tolerance through a debonding mechanism at the profile tips.

Novel zone-based hybrid laminate structures for high-velocity impact (HVI) in carbon fibre-reinforced polymer (CFRP) composites

M. Erfan Kazemi, Victor Medeau, Lorenzo Mencattelli, Emile Greenhalgh, Paul Robinson, James Finlayson, Silvestre T. Pinho

Summary: We introduce novel zone-based hybrid laminate concepts to enhance the high-velocity impact (HVI) response of baseline carbon fibre-reinforced polymer (CFRP) composites. By keeping approximately 80% of the baseline CFRP mass in the hybrid concepts, similar areal weights and substantial in-plane mechanical properties are maintained. Three zones are identified along the laminate thickness, and tailored materials are incorporated to improve the HVI response. Various materials, including carbon (thin- and thick-plies), glass, Zylon, ultra-high molecular weight polyethylene (UHMWPE), shape memory alloy/carbon fabric, and ceramic, alumina, and titanium sheets, are studied. All laminate concepts have comparable areal weights for meaningful comparison. Experimental results demonstrate up to 95% improvement in energy dissipation compared to the baseline quasi-isotropic (QI) CFRP configuration.

Masahito Ueda, Yuki Suzuki, Silvestre T. Pinho

Summary: The analytical method for calculating the axial compressive stress-strain relationship of a unidirectional carbon fiber-reinforced plastic (UD CFRP) was presented, taking into account the variability of the fiber misalignment angle. It was found that the load-bearing capabilities of different fiber groups decreased significantly with greater misalignment angles. Fibers with a misalignment angle of 0.5 degrees showed a large load drop after reaching their maximum loading, leading to ultimate failure.

Quasi-static compression tests of overwrapped composite pressure vessels under low velocity impact

Auwalu I. Mohammed, Kaarthikeyan Raghupathy, Osvaldo De Victoria Garcia Baltazar, Lawson Onokpasah, Roger Carvalho, Anders Mogensen, Farzaneh Hassani, James Njuguna

Summary: This study investigates the performance of composite pressure vessels under damaged and undamaged conditions, providing insights into their reliability and residual strength capabilities. The results demonstrate that the damage profile and its effect on compressive strength are similar between damaged and non-damaged cylinders. When subjected to quasi-static compression, the polyethylene liner absorbs enough elastic strain energy to recover without plastic deformation. Additionally, quasi-static compression has little to no influence on the axial strength of the cylinders. The damage characterization reveals fiber breakage, delamination, local buckling, and brooming failure. This study has direct implications for the safety design tolerances, manufacturing strategies, and operational failure conditions of composite overwrapped pressure vessels (COPVs).
