Finite Element Simulations of Compression After Impact Tests in CFRP Panels

Abstract

This study presents the development and validation of a finite element (FE) model to simulate the compression after impact (CAI) test of composite structures using Abaqus. The model integrates a detailed representation of the support system and employs a quasi-static analysis to simulate the compression phase. Simulations are aimed to predict the compressive failure load for a carbon fiber-reinforced polymer (CFRP) panel previously impacted at different energy levels. The simulations offer precise insights into postimpact structural performance. A key focus of the research was optimizing the model to achieve efficient computational costs without compromising accuracy. The FEM approach provides a cost-effective and time-saving alternative to physical testing. Results demonstrated the model's capability to accurately predict CAI behavior, highlighting its potential to streamline the design and testing processes for advanced composite materials. This work emphasizes the significance of FEM-based simulations in developing reliable and resource-efficient methodologies for assessing the structural integrity of high-performance components.
