| Popis: | We study the nonlinear behavior of a multilayer system subjected to the action of normally distributed surface loads. For this purpose, we use the numerical-analytic modeling of the nonlinear processes of deformation of three-layer systems. The nonlinear boundary-value problem with additional conditions in the form of inequalities is formulated in the variational statement. To solve the problem, we use the finite-element method combined with the Newton–Raphson method, and method of continuation in the parameter of loading. The stress-strain state is numerically analyzed for various thicknesses of the upper layer and the size of the loading zone. |
