Summary: The mixed mode fracture behaviors of TC4 titanium alloy were systematically studied by finite element method, testing, and theoretical analysis. It was found that there is II-III coupling effect ahead of the crack tip for mixed mode crack, and three-dimensional stress intensity factors were defined and calculated based on this. Under I-II mixed mode loading, the crack exhibited a planar propagation state, and the deflection angle increased with the mode II component. The I-II mixed mode fracture of TC4 showed a brittle fracture mechanism, and the brittle fracture criteria were in agreement with test results with some conservatism. However, under I-III mixed mode loading, the crack exhibited a spatial propagation state, and the deflection angle firstly increased then decreased with the mode III component. This is because the fracture mechanism shifted from brittle to brittle-ductile mixed fracture mode as the mode III component increased. The brittle criterion had a good prediction on I-III mixed mode brittle fracture behavior, with a low enough mode III component. The conclusions in this paper are of great significance to the mixed mode fracture evaluation of TC4 titanium alloys.

Summary: An extended non-ordinary state-based peridynamic (NOSB-PD) theory is used to study the fracture characteristics of rock-like materials with intermittent flaws under compressive-shear loading. The theory integrates stress-based failure criteria, namely the maximum tensile stress criterion and the Mohr-Coulomb criterion, to determine the tensile and shear failures of flawed rock-like materials. The distribution characteristics of maximum principal stress and shear stress obtained by the NOSB-PD theory are employed to analyze the fracture failure mechanism. The numerical results are validated by experimental data, indicating the capability of the extended NOSB-PD theory in simulating fracture processes under compressive-shear loading.

Summary: This study investigates the effect of quasi-static loading rate on the mixed-mode I/II fractures of rock materials. The results show that fracture toughness increases with increasing quasi-static loading rate, while crack initiation angle and fracture geometry remain relatively stable. A generalized maximum tangential strain energy density (GMTSED) criterion is proposed to analyze the development of fracture toughness and crack initiation angle. The experimental and analytical results support the validity of the GMTSED criterion.

Summary: Based on the criterion of local symmetry, a fracture in rock-type materials under pure shear will gradually grow to the direction where the local mode II loading is smaller, eventually resulting in a pure mode I fracture. However, predicting the fracture direction becomes challenging when the specimen size is small and the condition changes from small scale yielding to large scale yielding.

Summary: This study investigated the fracture properties of a high-strength steel with a body-centered cubic (bcc) crystal structure. The results revealed that both strength and ductility of the steel increased significantly at low temperatures. The material exhibited high plasticity at -196 degrees C during tensile tests using various specimens, while macroscopic brittle fracture occurred under high triaxiality scenarios. It was observed that the failure mechanisms transitioned from cleavage fracture to shear failure with decreasing stress triaxiality. A unified stress-state-dependent fracture criterion, which considers the transition of failure mechanisms, was proposed to describe the fracture properties of similar bcc materials at cryogenic temperatures. The threshold triaxiality for the transition of failure mechanisms was determined by the material's strain hardening capacity and fracture strength. Additionally, a probabilistic formulation incorporating the extreme value distribution was used to account for the statistical nature of cleavage fracture.

The study analyzed the effects of different viscosities and injection rates on fracture initiation and propagation, finding that high viscosity fracturing fluid at high injection rates can achieve hydraulic fracturing in high-permeability unconsolidated sandstone, and adjusting the viscosity and injection rate slightly higher than the threshold value can generate deep penetrating fractures in unconsolidated sandstones.

Summary: Fused deposition modeling is an additive manufacturing technique used for rapid manufacturing and prototyping. However, the layer-wise fabrication process often leads to anisotropic behavior in the final products. This research aims to determine whether the isotropic assumption of material using maximum tangential stress and mean stress criteria can predict the mixed-mode fracture resistance of 3D-printed parts. The results show that both criteria can accurately predict the fracture loads of the fused deposition modeling parts.

Summary: One complexity in rock engineering is predicting fractures in rocks with anisotropy in both elastic and fracture properties. This study proposes a fracture criterion based on a stress averaging procedure using a combination of the extended finite element method (XFEM) and the cohesive zone model (CZM) to predict fracture growth in anisotropic rocks subjected to mixed mode I/II loadings. The precision of the proposed model is evaluated by comparing its predictions with experimental results on Grimsel granite, and the effects of important model parameters are discussed.

Summary: This research focuses on the numerical investigation of fracture loads of U-notched specimens made of Al-6061-T6 and Al-5083 under pure opening mode and mixed mode I/II loading conditions. A new methodology is introduced to assess the notch fracture loads and crack growth path using the combination of the equivalent material concept (EMC) and extended finite element method (XFEM). The results are compared with a conventional elastic-plastic damage model, and the EMC-XFEM model is found to be more efficient and accurate in predicting fracture of ductile aluminum notches.

Summary: Moisture diffusion occurs in composite laminates when exposed to humidity, leading to a reduction in their mechanical properties, especially flexural stiffness, which is important in design. This research investigates the mechanical properties of CFRP and GFRP composites as a substrate in adhesive joints under cyclic wet/dry aging conditions for long-term structural applications. The results show that the reduction in flexural stiffness is more severe in CFRP laminates compared to GFRP laminates, indicating the suitability of GFRP laminates for ocean applications.

Summary: This work presents an analytical investigation of the damped forced vibration behavior of viscoelastic annular sector plates made of porous polymer foam. The motion equations are derived using the first-order shear deformation theory (FSDT) in conjunction with the energy method and calculus of variations. Three types of pore distribution in the plate thickness are explored, and the obtained relations are extended to constitutive equations using the standard linear solid (SLS) viscoelastic model. The system of equations with variable coefficients is solved using perturbation technique and Fourier series, and the asymmetrically dynamic response is computed analytically in a closed-form solution. Transient dynamic behavior of viscoelastic functionally graded porous (VFGP) annular sector plates is then analyzed for various loadings, and a user-defined field code is developed for reliability evaluation.

Summary: The research investigates the fracture behavior of brittle specimens weakened by V-shaped notches with end holes (VO-notches). Experimental investigation is conducted, and it is found that the size of the notch end-hole has an effect on the fracture resistance. Two stress-based criteria, the maximum tangential stress (MTS) criterion and the mean stress (MS) criterion, are developed for VO-shaped notches under mixed-mode I/III loading, and they accurately predict the fracture resistance of VO-notched samples with about 92% and 90% accuracy, respectively.

Summary: Cyclic loading significantly affects the durability of adhesively bonded joints, especially under cyclic impact loads. Low-energy cyclic impacts decrease the fracture energy of the joints, challenging the assumption of infinite life under cyclic impacts. The stress concentration caused by cyclic impact stress waves leads to a higher density of cracks at the specimen edges. Comprehensive inspections for bonded structures exposed to low-energy cyclic impacts are important to maintain joint strength and safe design and inspection practices.
