This work predicts bulk elastic properties and solves the wave function probabilistically using the density functional theory and by fixing outcomes with instrumented indentation. Revised bulk properties may predict crack start and propagation. Author-scripted pre- and post-processing in Abaqus simulated crack spread. Ultrasonic fatigue simulations increased fatigue life because the fracture onset phase was longer. We demonstrate that fatigue strength relies on elastic modulus because they are correlated. The verified results do not depend on any experimental evidence. Machine systems and scanning technologies have boosted the usage of selective laser-melted materials, leading to virtually full-density products. Microstructure and porosity from powder melting generate inconsistent mechanical performance under cyclic load. The extended finite element method was used to simulate crack propagation over an arbitrary fracture path to analyze fatigue crack development in additively generated fatigue specimens. Using fracture energy rate curves, loading level and testing frequency were evaluated on fatigue life. Micro computerized tomography (µ-CT) scans provide two-dimensional angular pictures. Several methods minimize faces and vertices. Open-source software was utilized to construct finite element models using µ-CT projections and to separate the cylindrical shell from internal pores. Crack propagation rate curves were used to investigate the impacts of loading level and testing frequency.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
