The Axial-Torsion Test is a multi-faceted mechanical testing process that applies both axial (longitudinal) and torsional (twisting) forces to a sample. This examination allows for a complex understanding of how a material behaves under various simultaneous stress conditions. . Set Up Environmental Chamber (if .
Background Using a thin-walled tube torsion test to characterize a material’s shear response is a well-known technique; however, the thin walled specimen tends to buckle before reaching large shear deformation and failure. An alternative technique is the surface stress method (Nadai 1950; Wu et al. J Test Eval 20:396–402, 1992), which derives a shear . The term “surround DIC” is employed to refer to multi stereo-DIC systems that allows for the measurement of the three-dimensional displacement field for all stress-free surfaces of a specimen. In the sequel, we present a specific system for carrying out tensile experiments on specimens with rectangular cross-section. 5.1.1. Experimental set-up
