The results of these works are required namely for the next development of the accoustic emission diagnostic method.  The aim of the presented work is to find the rules of the elastic wave propagation in a relatively more complicated body, more like a real structure. The thick-walled cylindrical vessel with the spherical bottom is modelled in the presented paper.  The time response of the vessel on the unit step force loading is calculated numerically, by using the Finite Element Method, here implemented into the computational system MARCIMENTAT The loading force imposes in the radial direction that is why we are dealing with the 3D problem. The special 2D case is solved too. In that case the loading force lies in the rotary symmetry axis. The results of computations are subsequently verified by confrontation with the results obtained from the experimental measurement on the real specimen using the transient broadband piezoelectric sensor.
