Abstract
This work explored combined tensile and torsional loads applied to additively manufactured Inconel 718 specimens employing Triply Periodic Minimal Surface (TPMS) structures. The gyroid TPMS unit cell was selected with two variations of cylindrical cell maps by varying arc count. The 4-arc and 8-arc structures were tested in an axial-torsion test frame at room temperature using equal parts of vertical and angular displacement control until failure. The data from the tests were compared to finite element analysis models to visualize when yielding was predicted. Finally, the fracture surfaces were investigated with a scanning electron microscope to characterize the primarily ductile fracture.
