Finite Element Modelling and Analysis of Low-Velocity Impact Behaviour in CFRP Panel

This article presents the development of a finite element model (FEM) to simulate low-velocity impact (LVI) tests on composite structures made of carbon fiber-reinforced polymers (CFRP). The analysis incorporates the modelling of key failure mechanisms in CFRP, addressing both intra-laminar and inter-laminar damage. The simulations aim to predict the coupon impact behavior across varying energy levels, significantly reducing the experimental costs and time required for material characterization. The results demonstrated the model capability to accurately simulate the LVI response, providing insights into distinct failure mechanisms at different impact energy levels. This study underscores the value of FEM-based simulations in creating efficient and reliable methodologies for evaluating the structural integrity of high-performance components.
