Nonlocal Damage Theory Based on Micromechanics of Crack Interactions

Journal of Engineering Mechanics, 1994
A nonlocal continuum model for strain‐softening damage is derived by micromechanics analysis of a macroscopically nonhomogeneous (nonuniform) system of interacting and growing microcracks, using Kachanov's simplified version of the superposition method.

A Statistical Micromechanical Theory of the Compressive Strength of Brittle Materials

Journal of the American Ceramic Society, 1978
A general theory of the compressive strength of brittle materials is presented. This theory proposes that failure is brought about by structural weakening from accumulated crack damage which increases with the stress level. The statistics of the flaw distribution and the mechanism of crack initiation and extension are important.

Aboudi’s Micromechanics Theories Applied to Multiscale Analysis of Composites

2009
NASA Glenn Research Center in Cleveland, OH has worked with Professor Jacob Aboudi since 1992 to develop and implement his micromechanics theories into a user-friendly software suite. This effort has resulted in the publicly available Micromechanics Analysis Code with Generalized Method of Cells (MAC/GMC) software, along with the coupling of the code ...

The Theory of Critical Distances: A link to micromechanisms

Theoretical and Applied Fracture Mechanics, 2017
Abstract The Theory of Critical Distances (TCD) is a methodology for prediction of the effect of stress concentration features on material failure, especially cracking-related mechanisms such as fatigue and brittle fracture. It has a long history but has become much more relevant to industrial problems in recent years thanks to the widespread ...
