Abstract

The aim of the current work is to develop a multiscale framework based on higher-order 1D finite elements developed using the Carrera Unified Formulation (CUF). The multiscale framework consists of a macroscale model to describe the global structure, and a CUF micromechanical model described using the Component-Wise approach. Such an approach allows for the explicit modelling of the fiber and matrix at the microscale, resulting in a high-fidelity finite element model at both scales. The use of refined CUF elements result in a computationally efficient analysis, due to a reduction in the degrees of freedom at both scales, as well as the reduction in total computational time when compared to standard 3D finite element analysis. The parallel implementation of the multiscale framework results in additional savings in computational time.
