This paper presents results of the numerical simulation modelling strength tests of laser-welded, foam-filled steel panels, performed by means of the Finite Element Method (FEM) within the frame of the ASPIS project. In this case application of the FEM makes it possible to significantly lower costs of determination of mechanical properties and optimization of the structure respective to its strength-weight ratio. The entire project as well as the presented calculations are aimed at implementing structures of the kind to shipbuilding industry. Results of the calculations modelling axial compression of panels comply with experiments qualitatively. The entire process of the structure’s compression till its collapse resulting from extensive plastic deformation within its middle zone, was step-by-step examined. Also, critical forces causing instability of the structure were determined. A partial quantitative discrepancy of the calculated reaction forces and those experimentally measured, requires further investigation
