Investigation into constitutive behaviour for thin sheet based micro forming

The present paper investigated the influence of t/d (thickness/average grain size) on yield stress and tangent modulus in the micro tensile test of CuZn36 sheets. By using the double-linear elastic-plastic constitutive equation, the constitutive relation of size effects was established. The relation...
