Source code for a program to calculate Schmid-factors
Beschreibung
Investigation on the mechanical properties of single crystalline Fe-34.7%Mn-13.4%Al-7.7%Ni-1.5%Cr (at.-%) shape memory alloy specimens revealed very good superelastic properties. The results of incremental strain tests show that the crystallographic orientation has a considerable impact on the superelastic performance, eventually resulting from the formation of twinned or detwinned martensite to accommodate strain as well martensite variant interaction. In situ optical microscopy images and the calculation of Schmid-factors allow for an in-depth assessment of the martensite phase transformation and the influence of martensite selection on recoverability. The calculation of the Schmid-factors can be based on the martensitic phase transformation that ideally follows the Kurdjumov-Sachs relationship. In order to allow these calculations to be easily transferred to different crystallographic orientations, the calculations performed were generalized and converted to a computer code. The program developed allows to determine the Schmid factors of all 24 possible shear systems as well as the corresponding trace angles that are left by the martensite phase on the surface. The program is freely accessible and available for use by anyone at
