Accounting for large membrane strains in Q4GS and T3GS elements in EUROPLEXUS
Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2016)This short note presents the updating of element thickness due to large membrane strains recently introduced in some shell elements (Q4GS and T3GS) of the EUROPLEXUS code (EPX). -
Description of the elasto-plastic material routine SGDI
Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2015)We describe the FORTRAN subroutine SGDI for rate-independent deviatoric plasticity with von Mises yield criterion and isotropic hardening, which corresponds to the VM23 material type in the EUROPLEXUS code (abbreviated as ... -

Casadei, Folco; Valsamos, Georgios; Larcher, Martin; Aune, Vegard (Research report, 2019) -
Generalization of the pinball contact/impact model for use with mesh adaptivity in EUROPLEXUS
Casadei, Folco; Aune, Vegard; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2016)This report presents the generalization of the pinball-based contact-impact model (PINB) of the EUROPLEXUS code for use in conjunction with mesh adaptivity, i.e. with adaptive mesh refinement and un-refinement. The interaction ... -
Numerical study on the structural response of blast-loaded thin aluminium and steel plates
Aune, Vegard; Valsamos, Georgios; Casadei, Folco; Larcher, Martin; Langseth, Magnus; Børvik, Tore (Journal article; Peer reviewed, 2016)The inelastic response of thin aluminium and steel plates subjected to airblast loading is studied numerically and validated against experimental data. Special focus is placed on the influence of elastic effects and negative ... -
Shock tube test with coupled 1D-3D models in EUROPLEXUS
Casadei, Folco; Aune, Vegard; Daude, Frederic; Galon, Pascal; Valsamos, Georgios; Larcher, Martin (EUR;, Research report, 2016)This report illustrates the use of coupled 1D-3D models for the simulation of shock tube experiments by the EUROPLEXUS code.
