Constitutive and transformation kinetics modeling of ε-, α′-Martensite and mechanical twinning in steels containing austenite
(2022)In the present study, a physically based constitutive and transformation kinetics model of stress assisted (SA) and strain induced (SI) ε-, α′-Martensite and twinning in steels containing austenite, is presented. The ... -
Detailed simulations of propellant slumping in the titanIV SRMU PQM-1
(2006)We utilize our tightly-coupled fluid/structure/combustion solid propellent rocket simulation package ("Rocstar") to study the unexpectedly large deformation of propellant at the center joint slot in a prequalification ... -
Incremental variational procedure for elasto-viscoplastic composites and application to polymer- and metal-matrix composites reinforced by spheroidal elastic particles
(2016)This paper presents an alternative formulation of the incremental variational procedure (IVP) of Lahellec and Suquet (2013) to estimate the macroscopic response and field statistics in elasto-viscoplastic composites. The ... -
Introduction
(2015)This introduction presents an overview of the history of migration within the Southern Balkan region since the end of Ottoman rule, in this way providing a broader context for the individual contributions. The existing ... -
A methodology for the estimation of the effective yield function of isotropic composites
(2016)In this work we derive a general model for N-phase isotropic, incompressible, rate-independent elasto-plastic materials at finite strains. The model is based on the nonlinear homogenization variational (or modified secant) ... -
Modeling of microsegregation and homogenization of 6xxx Al-alloys including precipitation and strengthening during homogenization cooling
(2019)Control of the homogenization process is important in obtaining high extrudability and desirable properties in 6xxx aluminum alloys. Three consecutive steps of the process chain were modeled. Microsegregation arising from ... -
TRIP steels: A multiscale computational simulation and experimental study of heat treatment and mechanical behavior
(2020)A multiscale investigation of the microstructure and the mechanical behavior of TRIP steels is presented. A multi-phase field model is employed to predict the microstructure of a low-alloy TRIP700 steel during a two-stage ...
