Abstract

Multiscale models have been demonstrated to be a solution when analysing hierarchic materials, such as composites, in which the different scales play a role in the structural problem. These approaches comprise a bottom-up transfer of information that links the analyses from the constituent level to the macroscopic structure. This manuscript proposes a methodology for conducting multiscale thermoelastic analyses of composite laminates in a computationally-efficient manner. For doing so, the Carrera Unified Formulation (CUF) is used to numerically model the different scales. On the one hand, CUF is coupled with Mechanics of Structure Genome (MSG) for providing the homogenised thermoelastic properties and retrieving the local stress state at the constituent level. On the other hand, two-dimensional CUF models are employed to predict the coupled thermo-mechanical performance of the macrostructural problem.
