| Abstract | |
This work presents geometrically-exact finite-strain shell models for the solution of large deformation shell problems. Finite rotations are treated by the Euler-Rodrigues formula in a fully exact way, and cross-sectional resultants are consistently defined. Both hiperelasticity and elastoplasticity are considered. A special displacement-based triangular finite element is introduced, over which the models are implemented. Locking is not observed as the performance of the element and accuracy of the formulations are assessed by means of several numerical examples. Excellent results are found. (AU) | |
