| 概要 |
Damage due to Low-Velocity Impact (LVI) in composite structures raises a maintenance concern because it can lead to invisible damage which contributes to catastrophic failure. Therefore, this study ai...ms to investigate the LVI damage behaviour of CCF300/epoxy composite using three-dimensional Puck failure criteria and gradual degradation law. The finite element model was developed using solid elements, and the simulation was done in Abaqus/Explicit platform. The simplified boundary condition was employed in the model to analyse the significance of the clamping zone in predicting the contact-force diagram. The performance of proposed failure criteria and evolution law was compared with experimental results and damage morphologies of inter- and intralaminar were observed and discussed based on failure criteria used in this paper. The results revealed that the computational analysis agreed well with experimental data using a simple boundary condition.続きを見る
