Summary: This paper focuses on modeling the water absorption and internal stress behavior of steel/rubber composites. A three-dimensional finite element model is established to accurately simulate water diffusion, and the outcomes show that the early water diffusion conforms to the Fickian model while the weight gain follows the Langmuir model due to the presence of bound water. The internal stress caused by differential swelling between steel and rubber is revealed and quantitatively analyzed, contributing to the understanding of damage initiation in steel/rubber composites.

Summary: The mechanical properties of natural fiber composites, particularly in corrosive or humid environments, were studied with a focus on the change in properties between normal and corrosive environments. Jute and banana fibers were the main natural reinforcements used, with glass fiber mats and aluminum foil also being used. Various composites were fabricated and their mechanical properties, including tensile and flexural strengths, were tested before and after immersion in seawater for sixty days. The results showed a deterioration of mechanical strength due to matrix erosion and the formation of micro cracks. Water absorption characteristics and diffusion coefficients were also determined. The findings were further supported by finite element analysis and SEM micrographs.

Summary: Riveted joints have different failure mechanisms, some related to the rivet itself, and others related to the materials to be joined. Stress concentrations at rivet holes play a significant role in failures of unidirectional composite materials. The orthotropic behavior of materials and non-linear contact conditions between the rivet and the hole make it difficult to provide a general solution to the problem.

Summary: This study investigates the thermal oxidative ageing effect of carbon fiber/epoxy plain woven composites using a hierarchical multiscale model. The model considers the deterioration of structural integrity caused by interface cracks at both micro- and macroscale, as well as the mechanical property degradation in the matrix. The results show that interface cracks and matrix degradation have a significant influence on the transverse and shear properties at the microscale, and the accumulation of interface and matrix degradation leads to reduced mechanical property in the mesoscale, particularly under shear loading. At the macroscale, both experimental and numerical results reveal different failure modes between the pristine and aged specimens under short beam shear loading, with interlaminar cracks formed during thermal ageing playing an important role in delamination failure.

Summary: This study develops a finite-deformation chemomechanical model to investigate the effects of mass diffusion on particle-reinforced composites. A general chemomechanical cohesive model is developed by considering displacement jump, chemical potential jump, and mass flux jump. The results show that the jump of mass flux across the interface leads to interface swelling, and an increase in the interface diffusion coefficient reduces the chemical potential jump. Changes in interface properties affect the diffusion rate. This research provides a theoretical reference for the application of particle-reinforced composites in chemical environments.

Summary: Wood is a widely available material that is extensively used as reinforcement in polymer composites. Wood polymer composites (WPCs) have various applications in different industries. However, measuring the properties of WPCs accurately is challenging, and finite element analysis (FEA) can help overcome this issue by predicting the mechanical properties of WPCs. Additionally, using simulation tools to predict material properties is a cost-effective technique for studying new materials under different load conditions.

Summary: Large segmental mandible bone defects present a challenge for endogenous regeneration, with individually manufactured scaffolds made of biodegradable magnesium alloys emerging as a potential treatment. Biomedical engineers face the challenge of developing a scaffold structure that not only provides stability, but also stimulates bone growth while considering the degradation of the magnesium alloy. The porosity of the scaffold must also promote bone ingrowth and neovascularization to support effective healing.

Summary: The etiology of subchondral bone cysts (SBCs) is not fully understood, but mechanical trauma and fluid pressure are believed to be two mechanisms for their formation and growth. Using a model of equine stifle joint, it was found that shear stresses are likely the cause of failure for the subchondral bone, not pressurized fluid from the joint. Additionally, fluid pressure must rise above what is likely to occur in vivo to increase bone shear stress.

Summary: In this paper, a new form-finding method based on spatial elastica model (FMSE) is proposed for elastic gridshells. The method integrates the deformations of elastic rods into the overall deformation of the gridshell, and solves a set of transcendental equations using the quasi-Newton method to ensure the deformation satisfies the given boundary conditions. The method is validated through experiments and expected to have potential applications in the investigations of elastic gridshells.

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).

Summary: This paper presents a study on six single-stringer specimens manufactured using the card-sliding technique with non-crimp fabrics and adopting a Double-Double (DD) stacking sequence. The specimens were tested under compression loading conditions to investigate post-buckling and failure in aerospace structures. Experimental results and numerical simulations were compared to analyze the behavior and failure modes of the specimens. The study found promising evidence of a viable solution to optimize aeronautical structures and enhance resistance to skin-stringer separation, particularly with the use of tapered flanges.
