Numerical Simulation on Interlaminar Fracture Toughness of 3D Printed Mortar Laminated Composites

  • 摘要: 通过有限元数值模拟研究了3D打印浆砌层合结构复合材料的层间断裂韧性。首先建立了基于内聚力原理和位移控制加载法的I型和II型断裂韧性有限元模型,模拟复合材料层间张开和错开的过程,随后通过有限元数值模拟与模型试验对比分析,验证了有限元数值方法的可靠性,最后分析了复合材料初始裂纹长度、断裂韧性、起始界面刚度、界面强度、黏结层厚度以及净距等参数对3D打印浆砌层合结构复合材料层间力学性能的影响。研究结果表明:对I型模型,减小初始裂纹长度、增大断裂韧性和增大黏结层厚度均能提高层间承载能力,起始界面刚度和界面强度的改变对拉伸力峰值无明显变化;对II型模型,减小初始裂纹长度、增强界面强度、增大断裂韧性和减小黏结层厚度均能提高层间承载能力,起始界面刚度的改变对荷载-位移曲线无明显影响。
