DETERMINATION OF THE STRESSED STATE OF RECTANGULAR ANISOTROPIC PLATES IN THE SPACE STATEMENT

摘要

We consider the problem of the stress-strain state of rectangular anisotropic plates in the space statement for one plane of elastic symmetry. The initial problem is described by a system of three partial differential equations of the second order. After separating variables and by using the spline-collocation method in two coordinate directions, we reduce the problem to a system of ordinary differential equations of high order with boundary conditions on edges. The obtained boundary-value problem is solved by the stable discrete-orthogonalization method. Results for the cases of rigid attachment and hinged support and for different geometries of plates are presented.
