Abstract
In this study, Quasi-Static Punch Shear Test (QS-PST) for AISI-304 stainless steel sheet material with 0.5 mm thickness was performed experimentally and numerically, then the results were compared. QS-PST was designed non-standard according to the need and is especially used to determine the puncture resistance of composite plate materials against low-speed loading. Since the results obtained from QS-PST are similar to those from ballistic tests, this has attracted the attention of researchers. The experimental study was carried out by integrating the die and punch which were specially produced for this test, into an electromechanical tensile-compression test device with a capacity of 100 kN. In order to define the material properties correctly in numerical analysis, the tensile tests of the relevant material were also carried out with the same device. Then, the CAD model of the experimental system was generated and Finite Element Analysis (FEA) was performed. In FEA, the mesh structure was determined as tetrahedral, since it gave closer results in such tests and the analyzes were performed by increasing the number of mesh from 16700 to 151800 elements. Finally, the experimentally and numerically obtained results were compared and it was observed that the result were very close depending on increasing the number of mesh.
