Modelling the Tensile Softening Behaviour of Concrete in LS-Dyna Software
IOP Conference Series: Materials Science and Engineering, 2020 Abstract The problematic of the paper focuses on the numerical modelling of tensile softening behaviour of concrete. For this purpose, the explicit finite element software LS-Dyna contains several nonlinear material models. The tensile softening behaviour of a total of four selected explicit nonlinear concrete models (namely the Concrete

On Applicability of LS-DYNA for Collision Analysis of Drifting Objects
Korea Society of Coastal Disaster Prevention, 2022 The characteristics of a secondary disaster are not well known with respect to the drift-impact by storm surge or tsunami. A numerical analysis for understanding the characteristics of a secondary disaster must be capable of simulating fluid dynamics as well as structural behaviors.
