The paper aims to investigate the effect of aluminium foam filling of hemispherical steel shell on its dynamic response, accounting for the blast pressure modelling. The considered structures subjected to uniformly distributed pressure, rigidly connected with a steel plate, are considered. True material stress–strain curves for shell and foam filling are assumed in calculations. The problem is solved by FEM using ANSYS software. The time relations of strain energy and effective stresses for different simulations of blast pressure are determined and compared for steel shells and shells filled with aluminum foam.
