Exploration of Several Influence Factors of Low-Velocity Impact Damage on Composite Laminates
摘要
Abstract
Damage of composite laminates due to low-velocity impact depends on number of factors. The simulation of composite laminates damage is carried out with ABAQUS software. Several influence factors are analyzed in order to foresee the damage resistance of composite laminates in the early stage with the method which regards damage area as the single-variable parameter. Delamination is one of leading damage forms of laminates. Based on damage mechanics, fracture mechanics and cohesive theory, cohesive unites are constituted in this paper to simulate delamination accurately. The point of inflexion is a central characterization of damage resistance. Based on the experiments and finite element model, damage resistances of different laminates are determined by contrasting diverse inflexion value which can be calculated on impact force-time curves. The rationality of the model has been confirmed by the low-velocity impact test.关键词
