| Abstract: | A problem is called mixed-mixed, when both normal and tangential displacements are prescribed on a part of the boundary, while the normal and tangential stresses are prescribed at the rest of the boundary. Exact closed form expressions have been derived for the resultant normal and tangential forces, tilting moment and torque, directly through the prescribed displacements, thus eliminating the need for determination of stresses. The problem solved treats a transversely isotropic elastic half-space, with arbitrary normal and tangential displacements prescribed inside a circle, and the rest of the boundary being stress-free. The interaction between an arbitrary force inside the half-space and a bonded punch is considered as an example. No similar result has ever been reported, even in the case of isotropy. |
