On the project

Explicitný riešič programu LS-Dyna umožňuje analýzu rázovo zaťažených betónových konštrukcií s využitím nelineárnych materiálových modelov. Sú k dispozícii rôzne úrovne detailnosti modelovania tejto problematiky. Cieľom projektu je preskúmanie parametrov numerického modelu v prípade využitia pokročilejších metód modelovania rázového zaťaženia (SPH, ALE). Bude prevedená analýza citlivosti a optimalizácia parametrov. Výstupy numerickej analýzy budú porovnané s experimentom podľa literatúry.
