Outline
This article proposes a method for calibrating and verifying interlayer parameters related to delamination in Carbon Fiber Reinforced Plastic (CFRP) laminates, as well as establishing a failure model based on *MAT_58. In terms of interlayer parameter calibration, the critical shear strain potential difference under interlayer failure is mainly extracted from the out of plane shear strain and normal strain cloud map of the short beam shear experiment to calculate the interlayer shear strength of composite materials. Furthermore, drop hammer impact experiments are conducted on the materials at 10 J and 200 J energy levels, as well as simulations of laminated shells and refined mesh sizes, to verify the effectiveness and modeling practicality of interlayer parameters. The results showed that the P16M2 model had a threshold load error of 5.09% and a peak force error of 8.99%, proving the effectiveness of interlayer parameters. Furthermore, based on the performance of each model in simulation accuracy and computational cost, increasing the number of layers of laminated shells is more effective than refining mesh sizes.
