摘要

The transient plane-stress response of a piezothermoelastic circular disk to axisym- metric heat input is investigated. Solutions to the equations of equilibrium and elec- trostatics are obtained using a potential function approach. The disk is assumed to exhibit hexagonal material symmetry of crystal class 6 mm. Initially the disk is at zero temperature; thereafter one face is exposed to linear heat transfer, while the opposite face is kept at zero temperature. Both faces are taken to be traction-free. The cylindrical edge of the disk is thermally insulated, electrically charge-free, and constrained against radial deformation.
