Abstract

In order to obtain the plastic constitutive equations of bulk amorphous alloy under complex stress state, tension, compression and torsion tests of Zr_41.2Ti_13.8 Ni₁₀Cu_12.5Be_22.5 bulk amorphous alloy are conducted and constitutive relations of one dimension are gotten. Plastic theories of continuum mechanics are applied to extend the constitutive equations of one dimensional of the compression and torsion tests to that of multi-dimensional respectively. The results show that the material exhibits Mises hardening characteristic. The plastic constitutive equations of the material under complex stress state can be derived by using the data of simple compression test or torsion test. The two constitutive equations based on compression and torsion tests are proved to be equivalent.
