摘要:
在已有三维机织圆管复合材料几何模型的基础上采用三维实体有限元方法,建立细观单胞模型模拟三维机织圆管复合材料在轴向拉伸情况下损伤的起始、扩展、直至最终破坏的全过程。采用改进的树脂传递模塑( Resin transfer moldling,RTM) 工艺制作了拉伸试件并进行了相应的试验。计算结果和试验结果吻合良好,均是纬向纱线横向首先产生破坏,并且应力-应变曲线都表现出显著的非线性特征,证明了研究方法的正确性。
Abstract:
A three-dimensional micro scale finite element method of 3D woven tubular composites is developed based on its micro architecture to simulate the damage evolution under the circumstances of axial-tensile load. The axial-tension experiments are done with samples made with reformative resin transfer moldling( RTM) technics. Good correlation is acquired between the calculation results and experimental data. The initial damage appeares in the weft yarn on transverse direction and the nonlinear properties is observably presented on the strain-stress curve. The numerical model is verified.
