A non-classical continuum approach to study the fragmentation of brittle solids
In this thesis, a non-local continuum approach coupled with the phase-field theory and Jones-Wilkins-Lee (JWL) equation of state (EOS) is proposed to model and simulate blast-induced fracture in brittle materials. Also, ... -
Non-classical continuum models for solids using peridynamics and gauge theory
This thesis focuses on three areas of nonclassical continuum mechanics of solids. In the first part, we develop a few peridynamics (PD) models and solution strategies for discretized PD equations in the context of the ... -
Non-classical mechanics and thermodynamics for continuum modelling of solids
This thesis dwells upon several aspects of continuum mechanics and thermodynamics to model elastic and inelastic response of solids. Broadly, the work presented may be categorized into two parts{ one focusing on the ... -
Non-Linear Finite Element Analysis Using Strain-Space Plasticity Coupled With Damage
(2011-01-27)The Thesis deals with Strain-Space Plasticity and its implementation in Nonlinear Finite Element frame-work coupled with damage. Conventional Stress-Space Plasticity, though very popular amongst commercial nonlinear FEM ... -
