Reinforced Concrete Impact Analysis in Ansys LS-DYNA

Reinforced concrete (RC) structures might be exposed to extreme dynamic loading conditions owing to impacts during their lives. Those loading conditions can be vehicle crash impact, tornado-borne debris, explosion impact, etc.
Impact on reinforced concrete slabs and members have been generally evaluated using empirical formulae to provided estimates on the extent of any impact damage. The empirical formulas proposed by various design codes are defined with respect to the impact parameters such as mechanical properties of the target, shape, diameter, velocity, mass and rigidity of the projectile. However, those formulas are limited to ranges of applications and some variables are not considered like dynamic response of structural members.

With the advancement finite-element theories in Ansys LS-DYNA® nonlinear dynamics structural simulation software’s explicit dynamic solvers are capable for addressing complex concrete impact simulations, providing a robust alternative to extensive physical testing.

This course details the procedure to perform impact analysis on Reinforced Concrete (RC) using Ansys Workbench LS-DYNA software where Reinforced Concrete (RC) beam is pin-ended supported subjected to impact by stainless-steel flat impactor.
