The generalized “method of lines” can be used for plates of variable thickness, in problems of dynamics and thermoelasticity. The basic idea is to reduce the dimension of the spatial coordinates using the projection method, with a system of basis functions. This article is the first part of the work. It shows the reduced differential equations and proposes a new way of modeling boundary conditions.en“metod of lines”method Bubnov–Galerkin–Petrov thermoelasticitythick platesstructural mechanicsметод прямыхметод Бубнова–Галёркина–Петроватермоупругостьтолстые плитыстроительная механікакафедра опору матеріалівArticle539.37:519.62]:624.073
