FINITE CIRCUMFERENTIAL SHEARING OF NONLINEAR SOLIDS IN THE CONTEXT OFTHERMOELASTICITY

The authors investigate the presence of 'boundary layer' like structur es wherein strains are confined adjacent to boundaries due to the circ umferential shearing of nonlinear elastic materials, in the context of finite thermoelasticity. It is found that even in the case of the cla ssical neo-Hookean model pronounced boundary layer structures are poss ible. For materials whose shear modulus depends on both the temperatur e and the stretch, it is shown that the effects can either reinforce o r mitigate each other. The problem considered here reduces to that stu died by Tao and co-workers (1992) for the isothermal case.
