Since the traditional damage model suffers from strain localization and it is impossible to get the unique Represetative volume
element (RVE) using local damage model. I have developed the novel explicit Nonlocal damage (NLD) model which is not only
mesh insensitive but also completely explicit. Hence it is computatinally more efficent compared to nonlocal damage model exist
in the literature. The fast algorithm and unique framework is developed and implemented in commercial FEA package Abaqus (VUMAT)
This model is coupled with failure zone averaging scheme to get the meso-scopic traction separation relation.
Developed the vectorised code based on the single equation radial return mapping algorithm
of local Lemaitre
ductile damage model. The code has been used to study the softening behaviour of unidirectional composite
RVE. From this study,
it is found that the multiscale damage and failure modelling can not be advanced by RVE using local damage
model as it
suffers from strain localization and mesh sensitivity. Strain localization is observed at plane oriented 45 Degree
with loading direction.
