The paper presents results of the FEM simulation of FSW process. The object of the research was a heat exchanger used for cooling of electrical components of propulsion systems. The tests enabled the obtainment of the field of temperature, stresses and displacements during the process and residual stresses and displacements of welded elements after cooling. Knowledge of the thermal conditions of the...
The article presents results of the FEM simulation involving friction stir welding (FSW) of check valve ball elements. The tests involved the obtainment of temperature fields, information about stresses and displacements during the process and about residual stresses and strains following the cooling of elements welded. The knowledge obtained concerning process thermal conditions and that concerning...
This paper presents methods and results of a simplified numerical simulation of collision process of containership’s side structure and a rock. Analysis of results of the modeling makes it possible to draw conclusions as to a character of the event as well as to estimate area and depth of damage caused by the penetrating rock, in order to select geometry of a filler and impermeable layer of 2nd protection...

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...
