Original Abstract

The paper deals with numerical simulation of penetration test called Small Punch Test (SPT). SPT is used to determine basic mechanical properties from a tiny piece of material. There are no generally accepted standards for this type of testing until now. The testing procedure drew a great interest in the last decade. “Code of Practice” was created based on the CEN Workshop 2007, which recommends both geometry, experiment performance and its evaluation. To obtain the mechanical properties from SPT is an indirect computational task. One of possible approaches to obtain yield strength and ultimate strength is the use of an inverse numerical simulation. There is a need to define the important variables that will substantially influence such inverse simulation.
