The precipitation hardened, high strength aerospace alloys (eg Al 7000 alloy series) suffer
from loss of fracture toughness due to the heat treatment leading to intergranular ductile …

Ductile fracture through growth and coalescence of intergranular cavities is a failure mode
observed experimentally in many metallic alloys used in industrial applications. Simulation …

Currently no systematic approach exists to explicitly quantify the combined effects of
anisotropic grain orientations and grain boundary behavior on the fracture of polycrystalline …

The process of void nucleation, growth, and coalescence is among the dominant ductile
failure modes in metallic alloys and can be transgranular as well as intergranular. In the …

A multiscale graph theory-based approach is introduced here to predict the microscale crack
path in polycrystalline materials. The crack path is represented as the boundary of the …

We present a simplified computational framework based on the cohesive finite element
method (CFEM) for predicting the macroscale fracture measures such as K IC and J IC of …

A theoretical two-dimensional (2D) model is proposed that describes the effect of grain
boundary (GB) segregations on the fracture toughness of nanocrystalline or ultrafine …

The resistance of polycrystalline materials to intergranular fracture depends on the
toughness of the interfaces between neighboring grains. Using finite element simulations on …

We introduce a novel computational framework designed to allow an experimentalist to
extract the local toughness associated with crack growth along an individual grain boundary …

Computational methods are rapidly emerging as an essential tool for understanding and
solving complex engineering problems, which complement the traditional tools of …
