Abstract in different language:	Description of the procedure and results are given for computer simulations of small punch test (SPT) performed on P92 structural steel. The maximum force calculated using the SPT simulation is about 5% higher than the measured value. The punch displacement at the maximum calculated force is 2% less than the measured punch displacement. Effects of several factors were analysed using the SPT simulation, such as friction between the test device and the test specimen, the geometry of the test device, and the clamping force. It was found that SPT results depend strongly on the amount of friction and on imperfections of the test device dimensions and geometry.
