碳纤维增强树脂基断裂的数值模拟研究

Study on Numerical Simulation of Fracture of the Carbon Fiber Reinforced Resin Matrix

基于断裂力学模型,通过应用Abaqus大型商用软件,建立碳纤维增强树脂基复合材料断裂实验的模型,计算了该模型的断裂韧性J积分,研究了用J积分来表征碳纤维增强树脂基断裂韧性特征,其结果表明了使用本文方法的有效性。

Based on fracture mechanics model, this paper, through the application of large com-mercial software of Abaqus, establishes an experiment model of carbon fiber reinforced resin matrixcomposites fracture, calculates the fracture toughness of the model J integral. J integral is used to studythe characterization of carbon fiber reinforced rein matrix fracture toughness characteristics; the resultsshow the effectiveness of using the method.
