| Abstract Scope |
In-plane torsion tests attract a lot of attention recently since it can avoid unwanted reaction torque compared with the traditional in-plane shear test. In this study, the in-plane torsion tests are used to strain different types of specimens to characterize plastic behaviors of sheet metals. For specimens with slits, strain hardening is calibrated up to large deformation by the finite element model updating (FEMU) technology with the experimental torque-torsion angle curves. Fracture strain is measured under shear by the in-plane torsion test. Cyclic shear loading tests are also carried out for multiple in-plane torsion test specimens to characterize the kinematic hardening behavior of sheet metals. This study shows that the in-plane torsion tests are a proper testing method to experimentally study the fracture in pure shear, the strain hardening at large deformation, and the kinematic hardening behavior under cyclic loading. |
