Finite Compression of Solids- Second Order Thermoelastic Analysis
نویسنده
چکیده
Abstract-In order to adequately reproduce the thermo-mechanical behaviour of metals under finite volume reduction and large temperature increase, it is necessary to use the second order thermoelastic analysis, i.e. to use the free energy function expanded up to the third degree in strain and tcmpcrature. Determination of the corresponding material constants is given and the resulting expressions are applied to the adiabatic compression of aluminum. The results are compared with those obtained from the first order theory.
