Title:
Wave criteria for ultratropic micropolar elastic solids
The paper is devoted to the problems concerning propagation of plane harmonic waves of translational and spinor displacements in ultratropic micropolar elastic solids. The concept of an ultratropic micropolar elastic body is discussed. An energy form of stress potential for an anisotropic micropolar elastic body is presented and constitutive equations for ultrahemitropic/ultraisotropic micropolar elastic solids are obtained. A systems of partial differential equations formulated by terms of the translational displacement vector and the spinor displacement vector for ultrahemitropic/ultraisotropic micropolar elastic solids is derived. The equations for wavenumbers of longitudinal and transverse waves propagating in ultrahemitropic/ultraisotropic micropolar elastic solids are obtained and discussed. A criterion for propagating transverse harmonic waves in ultratropic micropolar elastic solids is formulated.
