Numerical analysis of mine blast action on a vehicle
Abstract
The main objective of the present research is development of a preliminary numerical model
of dynamics and possible damage of a vehicle under the action of blast wave generated by the
activation of a landmine. Such a model should provide a valuable insight into complex
phenomena accompanied by detonation of a mine – pressure distribution in time, vehicle motion,
damage, etc. Numerical simulation has been performed using Abaqus/Explicit, FEM-based
software suitable for nonlinear processes with high strains, strain rates and energy densities,
which is typical for explosion effects. A representative case study of an explosion of 8 kg
explosive substance Composition B was analyzed. The explosion takes place under a vehicle with
the mass of 8 tons, with specific V-shaped body consisted from 10 mm thick armor steel plates.
The numerical model based on usage of Abaqus build-in CONWEP blast relations is described.
The results obtained show the displacement, and stress-stain field in ...the loaded vehicle, on the
basis of which the degree of damage to the target structure can be predicted. The guidelines for
the further work and model improvement are suggested.
