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.

Publikace se zabývá numerickou simulací penetračního testu zvaného Small Punch Test (SPT). SPT se používá k určení základních mechanických vlastností z malých vzorků materiálu. Pro tento typ testování doposud nejsou přijaty obecné standardy. Postup testování přitahuje v poslední dekádě velký zájem. Na CEN Workshop 2007 byl vytvořen "Code of Practice", který doporučuje geometrii, provedení experimentu a jeho ověření. Získání mechanických vlastností z SPT je přímá výpočetní úloha. Jeden z možných přístupů pro získání meze kluzu a meze pevnosti je použití inverzní numerické simulace. Je potřeba definovat důležité veličiny, které budou podstatně ovlivňovat takovou inverzní simulaci.
