Abstract
he dynamic problem of coupled physical and mechanical fields is considered in composites with joints of rough surfaces. By means of new proposed hypotheses of magnetic- (electro-/thermo-) elastic layered systems (hypotheses-MELS) the boundary problem is modeled for rough interfaces contact of continuous media with interconnected physical and mechanical fields. In various models of joints of thick piezoelectric layers combinations geometrically or physically heterogeneous surface layer is allocated in which the surfaceexponential behavior of physicomechanical fields or thermodynamic constants are given. The effect of surfaces roughness on the equations and the thermodynamic relations is achieved through the choice of surface-exponential functions (SEF). As an example the propagation of the shear wave signal is studied in an isotropic dielectric.
