Abstract : The oblique propagation of time-harmonic waves in a periodically laminated composite is studied. Governing equations are those of the coupled thermoelasticity theory for plane strain. The exact dispersion relation in the form of a determinant of order twelve is presented, and several numerical cases are included. Results indicating differing amounts of dispersion and attenuation for various angles of propagation are compared with results from an isothermal analysis. (Author)
