Geometrically nonlinear thermoelastic analysis of shells: modelling, incremental-iterative solution and reduction technique

Abstract. This work presents an accurate and efficient numerical tool for geometrically nonlinear thermoelastic analyses of thin-walled structures. The structure is discretized by isogeometric solid-shell model avoiding the parameterization finite rotations. An modeling thermal strains, temperature-dependent materials general temperature profiles proposed. Then, a generalized path-following method developed solving discrete equations with amplifier as additional unknown. Finally, reduction technique based on Koiter theory derived quick estimate buckling.
