VERIFYING MATERIAL MODELS OF CONCRETE AND REINFORCEMENT IN LS-DYNA SOFTWARE BY THE EXPERIMENTS

Abstract

This article presents research and evaluation of a number of concrete and reinforced material models commonly used in LS-DYNA to simulate reinforced concrete structures subjected to explosion pressures. Based on that, the selections of a suitable material model with the priority input for modeling are the basic parameters of the materials. Through the simulation results and the field explosion experimental data, the verifications and evaluations of the responses of the selected material models are conducted. The method developed for the simulation of the behaviour of the reinforced concrete slabs under  explosions using LS-DYNA is also presented in this article.
