Rubber Structure under Dynamic Loading – Computational Studies
This study focuses on the rubber structure behaviour assessment under dynamic load-
ing using numerical methods. Dynamic simulations of the TNT explosion under the tire-
suspension system were performed using the explicit LS-Dyna code using Arbitrary Lagrangian-
Eulerian formulation with Jones Wilkins Lee (JWL) equation defining the explosive material.
During analyses two different constitutive materials were used: Mooney-Rivlin without rate-
dependency and Ogden rubberlike material (MAT 181 Simplified Rubber) which includes strain
rate effects. Consequently, tire rubber material behaviour was investigated and compared for
two simulated cases.
