PLANE PIEZOTHERMOELASTIC RESPONSE OF A HYBRID LAMINATE - A BENCHMARK PROBLEM

Cylindrical bending of a composite plate, constructed of both orthotro pic and isotropic thermoelastic layers in combination with orthorhombi c piezoelectric layers, is studied in this paper. A recently derived e xact analytical formulation is employed to obtain a benchmark solution for the case of thermal and electric-potential surface loadings. A hi gh-order plane-strain analysis that accounts for transverse normal and shear deformation is also presented. Comparison is made of the displa cement and stress distributions found using the high-order and classic al bending theories with the piezothermoelasticity results. (C) 1998 E lsevier Science Ltd.
