Developing analytical methods for studying the strain state of flexible plates is a relevant issue, especially for complex problems that recognize nonlinear operation and temperature-dependent changes in mechanical properties of materials. The paper analyzes the stress-strain state of a two-field flexible plate with an initial deflection exposed to a non-uniform temperature field. It presents and analyzes the results of the numerical studies based on an algorithm developed by the authors for designing anisotropic rectangular structural elements with discontinuous parameters, taking into account nonlinearities. The analysis of the design results suggests that initial deflection, physical and geometric nonlinearities, as well as inhomogeneity of the plate material need to be taken into consideration.
