000015496 520__ $$2eng$$aNumerical simulation has been carried out to study the breakup of earth covered magazine due to internal detonation. As experimental study of such problem is very expensive, time consuming and with many limitations in scaling, data collections and analyses, numerical simulation using advanced modelling techniques provides a valuable alternative approach. In this study, the commercial dynamic solver LS-DYNA [1] is adopted to carry out the simulations of the magazine breakup by using the cohesive element model. The *MAT_COHESIVE_TH model in LS-DYNA is strengthened by implementing the strain-rate dependent characteristics of the concrete cohesive law. The simulation results are comparable with the test results.
