FE parametric study on the longitudinal tensile strength and damage mechanism of Z‐pinned laminates
Source abstract
Abstract
Abstract A new periodic unit cell model was proposed to quantify the longitudinal tensile strength of laminates with different Z‐pin parameters. A modified three‐dimensional Hashin criterion was used to predict the failure of the laminate and Z‐pin, while maximum stress criterion was utilized to analyze the damage in the resin‐rich zone. Benchmark tests were carried out to verify the model, and finite element (FE) results agreed well with the experimental data. Hence, a parametric study was carried out to examine the influence of Z‐pin parameters on the longitudinal tensile strength and damage mode of unidirectional laminates. FE results show that the changing trend of the tensile strength against Z‐pin parameter is obviously more complicated than that of the modulus and is related to the change of damage mode or microstructure.
