Modelling the interfacial damage of carbon fiber reinforced polymer composite laminate under the low-velocity impact loading

Abstract

This paper presents the performance of three-dimensional Puck failure criteria emphasising on the gradual degradation law to predict the structural responses, as well as the onset and propagation of failure due to different interface modelling technique. The proposed damage model is performed using Abaqus explicit analysis. Four different cohesive models are analysed using three-dimensional finite element model based on low-velocity impact loading. The structural responses are compared with experimental data taken from literature to measure the performance of such damage model. It is found out that the model adopted here responses well with test curves and demonstrates the high capability of predicting the damage in the direction of in-plane as well as out-of-plane in a composite laminate. The simplified model using combination of tie-cohesive layer technique demonstrated the balance performance between the quality of the result as well as calculation time.

Numerical analysis of wave processes under high-speed impact on an object from CFRP

“…Even more important thing is the anisotropic behavior composite materials [3][4][5][6]. In particular, upon impact, energy transfer through the material in the form of wave processes will inevitably occur.…”

Study on the compressive residual strength after edge low-velocity impact of T300/69 laminates

“…In daily application, a low-velocity impact (LVI) event is one of the silent contributors to the usage performance of the composite structure (Meon et al ., 2021; Tuo et al ., 2019). Complex barely visible indentation damage (BVID) (Thorsson et al ., 2018a) leads to a reduction in safety performance when it occurs inside the laminate, such as matrix cracking and delamination.…”
