Abstract
The chapter presents numerical assessments of physically nonlinear problems through a class of refined one-dimensional theories based on the Carrera Unified Formulation (CUF). CUF is a hierarchical formulation to generate refined structural theories through a variable kinematic approach. Physical nonlinearities include von Mises plasticity and cohesive interface modeling for delamination of composites. This work aims to provide insights into the effect of kinematic enrichment on the overall nonlinear behavior of the structure. Guidelines stem from the evaluation of the accuracy and numerical efficiency of the proposed models against analytical and numerical approaches from the literature.
