层合板有限元分析中的非线性控制

Nonlinear Control of Finite Element Analysisin in the Laminate

本文主要利用ABAQUS调用USDFLD接口子程序模拟复合材料层合板的性能,并将实际实验数据和直接模拟结果进行对比,调用用户子程序,模拟计算结果与实际实验结果取得了很好的一致性,说明在层合板性能有限元分析中非线性控制的重要性。

Using the USDFLD subroutine interface of ABAQUS simulated the performance of composite laminate in this paper, Real experimental data and direct simulation results were compared. Using the USDFLD subroutine interface of ABAQUS , these are good agreements between FEM calculation and real experimental results. The importance of non - linear control was shown in the finite element analysis of laminate performance between experimental observation and FEM calculation.
