Název v původním jazyce

Prediction of static materials properties of P92 steel based on small punch test

Popis výsledku v původním jazyce

Small punch testing under constant deflection rate of P92 steel at room temperature was performed. The experimental SPT curves were used for prediction of yield and ultimate strength based on empirical formulas published in the literature and also by numerical inverse analysis with help of finite element method. Conventional tensile tests were performed for verification of the data derived from small punch testing. Good agreement was found in the case of ultimate strength. Determination of the yield strength is less accurate mainly due to significantly lower values of force at yield compared to maximum force measured by SPT. Two approaches for evaluation and determination of the force at yield limit in SPT diagram and estimation of the yield strength of the material are described in the article.
