Multi-scale reliability-based design optimisation framework for fibre-reinforced composite laminates

Abstract: Purpose The purpose of this study is to enable performing reliability-based design optimisation (RBDO) for a composite component while accounting for several multi-scale uncertainties using a large representative volume element (LRVE). This is achieved using an efficient finite element analysis (FEA)-based multi-scale reliability framework and sequential optimisation strategy. Design/methodology/approach An efficient FEA-based multi-scale reliability framework used in this study is extended and combined with… Show more

“…Designing and analysing FRP composite materials is a more complicated process than metal alloys due to their multi-material build-up nature, which introduces more design variables [57]. For instance, designing alloy adherend will typically have the overlap thickness as the primary material design variable.…”

“…Their inherent and irreducible nature classifies them as aleatory uncertainties, often defined in the form of a probabilistic distribution [32]. If these uncertainties are not accounted for, composite performance at the joint will be non-optimal, potentially leading to poor reliability and failure [57]. The traditional approach to account for these uncertainties is to use safety factors.…”
