SPT results evaluation
Original language description
Small punch test (SPT) is known as a powerful NDT tool for material properties determination of existing structures. The paper presents a description and results of SPT computer simulations performed with the steels in a wide range of yield strength andtensile strength. The true tension diagrams of these steels are created by the Hollomon's formula. Conventional mechanical properties of the steels are verified from the results of computer simulation of tensile tests, too. True mechanical properties areused for SPT simulation of steels. Relationships of loads and puncher displacements are shown in the paper. Subsequently parameters SPT, i.e. the maximum load, puncher displacement at maximum load, plastic tangent at the initial stage of SPT and "yieldload" are carried out. Intersection of plastic tangent and axis of load determines "yield load". Causal relations between the characteristics of static strength steels and SPT parameters are shown as graphic results. Quite notable is the
