Abstract:
In this paper, the elastic response of a surface-stiffened transversely isotropic half-space subjected to a surface normal load is addressed. The half-space is reinforced by a Kirchhoff thin plate bonded to its surface. Two different boundary conditions are considered across the plate-half-space interface: (i) the classic approach in which the plate in-plane deformation is neglected by writing the interfacial boundary conditions across the plate mid-plane, and (ii) the refined approach that considers the in-plane deformation of plate due to bending by writing the boundary conditions across the bottom face of plate. By virtue of appropriate displacement potentials, the complete set of elastic fields of the problem are expressed explicitly in the form of semi-in finite line integrals. The limiting case of the problem corresponding to the isotropic half-space is also obtained. The obtained results are verified with the available solution in the literature. According to the numerical results, the effects of anisotropy, type of loading, and bonding assumption are discussed
