The Damage Evolution of the Flange Repaired Reinforcement Laminates

Article Preview

Abstract:

The Finite Element Model (FEM) study of the flange repaired cut-out laminates were carried out in this work. The FEM studies on the reinforcement and unrepaired structure is focused on simulation of the tensile test, damage evolution and the predicted failure loading. The test results indicated that the strain value decreased as the size of load is. The simulation results show that the tensile strength of the reinforcement is larger than that is unrepaired. Compared the results of damage evolution with four kinds damage criterion, the major failure model is matrix cracking under transverse tension appeared in the layers.
