Semimicroscopic Study on Inelastic Behavior of Polycrystalline Metal under Varying-Temperature Conditions

抄録

In the first part of this work, the inelastic behaviors of aluminium alloy were investigated experimentally using thin-walled tubular specimens subjected to combined loads of axial force and torque under varying-temperature conditions. The temperature selected was between room temperature and 250°C. The strain rate was controlled so as to be constant (3×10^-5/sec). In the second part, the behaviors observed under such complex conditions were confirmed to be reproduced by a set of constitutive equations derived on the basis of crystal plasticity.
