Coupled thermoelastic analysis using 1D higher-order structural theories and finite elements

Martina Santori

Abstract. This paper presents solutions to coupled thermoelastic dynamic problems of beams subjected to thermal loads over time. A higher-order one-dimensional (1D) model in the framework of the Carrera Unified Formulation (CUF) is used. The study aims to provide accurate predictions for displacement fields and temperature changes within homogeneous isotropic structures under thermal loads. A numerical test case describing the influence of sudden heating on the response of beam structure is presented. The results of the quasi-static analysis are compared with the dynamic response. Different two-dimensional Lagrange expansions are used to discretize the beam cross-section. The approach used in this work simplifies the complex three-dimensional (3D) problem into a computationally efficient 1D model.
