This doctoral thesis aims to provide a comprehensive analysis of the role of porous
microstructure on dynamic shear localization and ductile failure. For this purpose, a …

For more than six decades, improving the strength and ductility of industrially important
materials has been in the focus of research. Besides economic reasons, safety issues have …

The complex deformation processes and high plastic anisotropy of magnesium (Mg) and its
alloys are often referred to as the origins of poor ductility under general loading conditions …

In the present work, we have analyzed the effect of anisotropy on void growth and stress–
strain behavior for materials that exhibit remarkable tension–compression asymmetry (ie …

This paper presents a finite-strain homogenization model for the macroscopic behavior of
porous polycrystals containing pressurized pores that are randomly distributed in a …

This thesis investigates damage development through void growth in porous, ductile
materials, both for conventional isotropic materials and materials exhibiting gradient …

RESPONSE OF ELASTO-VISCOPLASTIC POLYCRYSTALS Shuvrangsu D Page 1 …

In all the constitutive models for porous plastic materials presented in previous chapters, it
was presumed that the matrix can be regarded as isotropic. However, most engineering …

The crystal plasticity finite element method was used to investigate cylindrical void growth
and coalescence in face-centered cubic single crystals. In the finite element model, a …

Void growth and morphology evolution in fcc bi-crystals are investigated using crystal
plasticity fi? nite element method. For that purpose, representative volume element of bi …
