摘要
层合板(±45°/90°/0°)是准各向同性层合板,其刚度在板面内各个方向上都相同。使用计算软件,编写程序代码,运用有限元的方法,划分有限元网格,计算了层合板(±45°/90°/0°)的纵横剪切模量[1]。将计算结果与复合材料纵横剪切模量试验结果进行对比,得到数值模拟和试验结果之间的误差为0.89%,一致性很好,说明该计算方法可用于工程计算模拟。
Laminated plates(±45°/90°/0°)are quasi isotropic laminates with the same stiffness in all directions within the plate plane.Using computational software,program code was written,and finite element method was used to divide the finite element mesh and calculate the longitudinal and transverse shear modulus of laminated plates(±45°/90°/0°)[1].The calculated results are compared with the transverse and longtitude shear modulus test results,it was found that the error between the numerical simulation and experimental results was 0.89%,indicating good consistency,indicating that this calculation method can be used for engineering calculation simulation.
