Numerical Simulation of Dominant Fracture Mechanisms in a Nickel-Based Alloy XH73M within the Phase Field Approach

Adaptive anisotropic phase field modeling of dynamic fracture in polycrystalline materials

Investigating Fracture Behavior of Lattice Structures Using the XFEM and Equivalent Solid Material Model Techniques

This study aims to numerically investigate the mode I, II, and III fracture behaviors of additively manufactured degradable, bioplastic polylactic acid (PLA) lattice specimens. Numerical simulations were performed using the eXtended Finite Element Method (XFEM) based on the extracted PLA's mechanical and fracture mat...

Stress Corrosion Cracking and Grain-Scale Deformation Mechanisms of FSW Joint of 7A52 Aluminum Alloy

This paper investigates the stress corrosion cracking (SCC) behavior under constant loading conditions and the early-stage grain-scale deformation mechanisms of a friction-stir-welded (FSW) joint of 7A52 aluminum alloy. The results show that when a constant load equivalent to 1.0 times the yield strength (439.43 MPa) o...

Numerical Investigation of Time-Dependent Deformation and Fracture Evolution in Flawed Sandstone

Research on the Stability of Arc-Fractured Rock–Concrete Composites: Mechanical Response and Energy Evolution

To mitigate the violent movement of overlying strata in goaf areas, rock–concrete composite support systems are widely utilized. However, the mechanical behavior of such systems under the influence of complex pre-existing defects, such as arc-shaped fractures, remains insufficiently understood. This study aims to c...

Crack growth and fracture characteristics of riveted dissimilar aluminum joints under mode I loading

Crack initiation and propagation in aerospace structures can compromise structural integrity and service safety, making fracture assessment an important aspect of joint design. Riveted aluminum joints are widely used in engineering structures; therefore, understanding their crack-growth behavior under different loading...
