Development and numerical implementation of nonlinear viscoelastic-viscoplastic model for asphalt materials [PDF]
, 2009 Hot mix asphalt (HMA) is a composite material which consists of aggregates, air voids and asphalt materials. The HMA response is typically described to be viscoelastic-viscoplastic, and its response is a function of temperature, stress/strain rate, and ...

Coupled Gradient Enhanced Damage - Viscoplasticity Model Using Phase Field Method
, 2015 The aim of this dissertation is developing a framework to describe damage evolution as a phase transformation in solid materials and couple it to the well-known Perzyna type viscoplastic model to account for inelastic behavior of ductile materials.

COMPARISON OF SOME PLASTICITY THEORIES BY MEANS OF THE FINITE ELEMENT METHOD
, 1984 This paper deals with six plasticity theories by means of finite element method. These are the time-independent theory of Prandtl-Reuss, Hencky-Nadai, Ilyushin and Valanis and the elasto-viscoplastic theory of Perzyna and Krempl.
