Computational Simulation of Small Punch Test
The paper deals with numerical simulation of Small Punch Test (SPT). SPT is a penetration test used to determine basic mechanical properties from a tiny piece of material. The testing procedure drew a great interest in the last decade, nevertheless there are no generally accepted standards for this type of testing until now. “Code of Practice” was created as a consequence of the CEN Workshop 2007, recommending both geometry, experiment performance and its basic evaluation. To obtain other mechanical properties like flow curve, yield stress, ductility and ultimate strength, it is necessary to realize a numerical simulation of the test to identify the mentioned material parameters. As the SPT results are generally influenced by many other parameters besides material behaviour, we try to quantify their relevance to make the material identification more rigorous.
