The resolve of many important problems in practice that arise modern technology cannot always be obtained by traditional methods analytic function theory or means integral transformations. This applies, for example, to contact problems, which take into account the finite size region at least one direction, investigate environments with curvilinear anisotropy and like. mathematical elasticity ar...

Starting from a general classical model of many interacting particles we present well defined step by procedure to derive the continuum-mechanics equations nonlinear elasticity theory with fluctuations which describe macroscopic phenomena solid crystal. As relevant variables specify coarse-grained densities conserved quantities and properly displacement field describes local translations, rotat...
