Review of methodologies for composite material modelling incorporating failure

Abstract

Advanced composite materials are finding increasing application in aerospace, marine and many other industries due to the advantages in performance, structural efficiency and cost they provide. However, despite years of extensive research around the world, a complete and validated methodology for predicting the behaviour of composite structures including the effects of damage has not yet been fully achieved. The Cooperative Research Centre for Advanced Composite Structures (CRC-ACS) is leading a currently running collaborative project to develop a methodology for determining mechanical behaviour and failure in composite structures. Key drivers of the project are the use of multi-axial testing machines for material characterisation and an appreciation of the issues involved due to the different length scales of any analysis. As part of the project, a critical review was performed to assess the state of the art in material constitutive modelling and composite failure theories. This paper summarises the results of the review, which includes a discussion of the various theories and approaches within the context of the dissipated energy density framework. The results of the review will be applied within the project to select appropriate constitutive modelling and failure approaches for implementation within a data-driven material characterisation methodology.

Optimal Design for a Composite Wind Turbine Blade With Fatigue and Failure Constraints

“…A good review that summarizes the state of art in composite failure criterions is by Orifici et al [36]. In [36], the failure criterions are categorized based on strength or fracture mechanics theories, failure mode prediction, or whether they focus on in-plane or interlaminar failure.…”

“…A good review that summarizes the state of art in composite failure criterions is by Orifici et al [36]. In [36], the failure criterions are categorized based on strength or fracture mechanics theories, failure mode prediction, or whether they focus on in-plane or interlaminar failure. Comparing the different failure criteria with each other for the purpose of our application -wind turbine blade -is a difficult task, which requires extensive experimental tests across the possible loading scenarios.…”

Static and Fatigue Failure of Bolted Joints in Hybrid Composite-Aluminium Aircraft Structures

“…A vast number of composite failure criteria has been introduced over the years, covering both intralaminar and interlaminar failure, where some of them are reviewed in [59]. An assessment and comparison of the predictive capabilities of a large number of existing intralaminar failure criteria was conducted in [60] in a World-Wide Failure Exercise (WWFE).…”

Analysis of damage localization in composite laminates using a discrete damage model

“…Several phenomenological criteria have been developed, many of which consider several failure mechanisms such as fiber breakage, fiber buckling, and matrix cracking, [3]. These formulations have been used for modeling brittle composites such as CFRPs subjected to different load states [4 7].…”
