Numerical Investigation of Compressive Strength of Structural Steel Material Under Different Loads According to ASTM D695 Standard

In order to determine the mechanical properties of materials according to certain standards, numerical analysis methods are frequently used in addition to experimental studies. In this study, the compressive strength test was numerically modeled in a computer environment according to the ASTM D695-15 standard. Analyses were carried out by defining structural steel material for the plate designed with the specified standard dimensions and 1 mm thickness. In the numerical analysis, two different loading types, force and displacement, were examined. Numerical analyzes were carried out in a total of twelve different situations by applying 2, 4, 6, 8, 10 and 12 N compressive forces in the analyzes where force load (FL) was applied, and 1, 2, 3, 4, 5 and 6 mm compressive displacements in the analyzes where displacement load (DL) was applied. The effects of different loading types and different loading intensities on the compressive strength of the test specimen were investigated. In all analyses where FL and DL were defined, it was determined that as the FL and DL intensity increased, the stresses and total deformation on the test specimen also increased.
