Sensitivity analysis of small punch test

Abstract eng:
Small Punch Test (SPT) is used to determine current values of basic mechanical properties from a tiny piece of material. This non-standard type of test is preferred if there is shortage of material for samples. It is common for example when testing components of nuclear power plants, turbines, rotors, etc. It is an indirect computational task to obtain the mechanical properties from SPT. One of possible approaches to obtain yield stress and ultimate strength is the use of an inverse numerical simulation. There is a need to define the important variables that will substantially influence the inverse simulation.
