Finite element modelling of low velocity impact test applied to biaxial glass fiber reinforced laminate composites

• High-speed imaging and DIC are used to track damage progression during impact test A proposed 3D FE model allows predicting the behavior of laminate composites [0/90] 3s laminates failed due fiber breakage at high compression impacted region [±45] exhibited matrix cracking delamination caused by tension The aim this paper is describe dynamic biaxial glass reinforced under low velocity through finite element modelling. Experimental investigations performed using an instrumented drop weight testing machine were conducted on three-point bending composite samples in order assess their resistance. Moreover, experimental setup allowed visualization real-time via high-speed camera Phantom V2512 enabling capture 83000 frames per second. Dynamic strain fields extracted Digital Image Correlation (DIC) method. Based results, a numerical study specimens was developed as user subroutine VUMAT integrated ABAQUS/Explicit precisely progressive failure test. In model, each ply accounted Hashin damage-based behavior, cohesive zone employed onset inter-laminar delamination. good experimental-numerical correlation obtained for peak force modes.
