Coupled Thermo-Mechanical Numerical Modeling of CFRP Panel under High-Velocity Impact

Advanced composites have a brittle nature making them highly susceptible to failure and propagation under impact loading conditions. Appropriate modeling techniques accurately simulate these conditions are required. This study presents examines coupled thermo-mechanical technique its associated numerical simulations for analyzing carbon fiber-reinforced composite panels subjected high-velocity impact. The essential parameters necessary the selected configuration determined through physical-based approach, which has not been previously reported. By following proposed framework, conventional trial-and-error calibration process that relies on an extensive testing campaign is minimized. A stacked shell-cohesive methodology applied T800/F3900 unidirectional fiber/epoxy panel with 16 plies in quasi-isotropic layup [(0/90/45/-45)2]s. flat was manufactured according ASTM D8010 standards. Both condition progressive damage analysis explored discussed comparison experimental test cases available open literature. Thermal effects mechanical performance of targets also based application constitutive transient thermal coupling method LS-DYNA®. contact heat generated by conversion impact-induced kinetic energy projectile evaluated analyzed. New observations regarding techniques, transfer, mechanisms target plates offered. Additionally, findings related changes material characteristics resulting from transfer discussed.
