Abstract

This paper presents an advanced modelling approach for the prediction of residual stresses and process-induced deformations. The numerical model is based on the Carrera Unified Formulation, a numerical tool that allows any kinematic model to be considered without an ad hoc implementation. The evolution of the material properties during the process is obtained by the RAVEN software. A cure hardening instantaneously linear elastic (CHILE) constitutive model was adopted to investigate the magnitude of residual stresses and deformations. The results have been compared with those from the literature. In addition, Different laminations have been investigated and compared.
