Finite-element matrix equations based on the Lagrangean, first-order, incremental plate equations of motion superposed on homogeneous thermal strains were formulated using virtual work principles. A program for an isoparametric, four-node quadrilateral element was written and applied to the study of the F-T behavior of flexure mode quartz resonators. Numerical results are compared with experimental results and the three-dimensional finite-element results.
