The critical effect of micro level defects should be examined at macro level to better
understand the fracture behaviors of engineering materials. This study investigates the …

The influence range of crack interaction is studied using the distribution dislocation
technique, and is defined as the influenced zone. For elastic materials with cracks, the …

The dynamic fracture behavior of brittle materials that contain micro-level cracks should be
examined when material subjected to impact loading. We investigated the effect of micro …

The matrix component of composite structures is generally brittle. In any damage
occurrence, fracture propagates rapidly through the structure. This study proposes a novel …

The solution of an infinite plane containing an arbitrarily located micro-crack and a kinked
macro-crack is presented based on the distributed dislocation technique (DDT). The stress …

Accurately assessing fatigue crack growth resistance of structural materials is critical for
service safety. We developed a theoretical model to describe the fatigue crack growth rate …

In an effort to semi-analytically estimate the effective plastic zone size around U-shaped
notches under mixed mode I/II loading by using the Tresca and Von-Mises yield criteria …

The interaction between the main crack propagation and micro-defects (ie dislocations,
grain boundaries and nanocracks) under uniaxial tensile load is investigated theoretically …
