抜粋

Micro scale torsion test method was developed to investigate continuous deformation behavior around initial yield point of copper single crystal structure. Continuous load-displacement curve was obtained by torsion test because dislocation burst phenomenon was suppressed by stress gradient and torsion stress direction which parallel to the specimen surface. In case that new constitutive law was applied to the simulation, crystal plasticity parameter of copper could be evaluated by parameter fitting which using load-displacement curve of experiment and simulation.
