AMOG was commissioned by LEA to develop a LS-Dyna numerical model to simulate the performance of the M113 vehicle under a landmine explosion event.
Two blast events were considered for correlation namely, the Belly Blast event with the charge being located along the centreline of the vehicle and the Track Blast event with the charge located beneath the front left wheel.
The blast event was modelled using the Arbitrary-Lagrange-Euler (ALE) approach which explicitly models the pressure wave generated by the detonation products through the soil and air. Blast energy is transferred to the vehicle structure using Fluid-Structure Interaction (FSI).
