Thermal Disturbances in Twinned Orthotropic Thermoelastic Material
International Journal of Applied Mechanics and Engineering, 2018 This paper deals with deformation in homogeneous, thermally conducting, single-crystal orthotropic twins, bounded symmetrically along a plane containing only one common crystallographic axis. The Fourier transforms technique is applied to basic equations
