On the Variational Principle of Lagrange in the Micropolar Theory of Elasticity at Nonisothermal Processes.

In this paper, a variational principle of Lagrange, the Ritz method, and piecewise polynomial serendipity shape functions are used to obtain a stiffness matrix and a system of linear algebraic equations in the micropolar theory of elasticity for anisotropic, isotropic, and centrally symmetric material in case of a nonisothermal process.
