Estimation of the stress-strain state of orthotropic plates on elastic foundation using the bimoment theory

The study is devoted to the development of bimoment theory and method for calculating thick plates in framework three-dimensional elasticity. basic relations equations motion plate presented are constructed with respect forces, moments bimoments arising from nonlinearity law distribution displacements stresses over thickness. Bending vibrations isotropic orthotropic considered an example calculations. resulting solution showed efficiency accuracy proposed assessing stress-strain state plates.
