摘要：
A novel peridynamic model for predicting thermomechanical behaviour of three-dimensional shell structures with 6 degrees of freedom has been proposed. Also, a numerical algorithm for dealing with complex shell structures is provided for the first time in the peridynamic literature. The peridynamic damage criterion based on critical energy release rate is provided for shell structures. The capability of the developed peridynamic model is demonstrated by predicting deformations for a flat shell, a curved shell, and a stiffened structure. To further demonstrate the capabilities of the proposed model, damage on flat shell in a double torsion problem, flat shell with pre-existing crack, thermal fracturing of a glass cup and damage in a dropped egg are simulated.
