ABSTRACT 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 material properties.

Fatigue Crack Modeling of Railheads Using a Nonlinear Cohesive Zone Model
ABSTRACT Subsurface fatigue crack growth within railheads can be deleterious leading to catastrophic failures in rails. This study aims to model the fatigue crack growth originating at the subsurface level within railheads. Towards that end, a finite element modeling approach is utilized wherein complex crack growth is explicitly modeled using a ...

ABSTRACT In this study, the fracture response of polypropylene (PP) was assessed using J‐integral evaluation, J‐R curve construction, and fractography examination. J‐R and load–displacement curves were analyzed to determine critical loads and estimate J‐integral values based on standards established for polymer fracture testing, which led to the ...
