| 摘 要： | 为了描述复合材料用机织物在大变形下由于经纱和纬纱之间角度变化所引起的非线性各向异性材料行为,前期工作中建立了一个非正交本构模型.利用半球形冲头对复合材料用平纹机织物进行冲压模拟,并将非正交本构模型和正交本构模型的模拟结果与实验结果进行对比,对非正交本构模型进行验证,以充分说明该模型的有效性和正确性.结果表明:采用非正交...

| Abstract: | A non-orthogonal constitutive model,previously developed by the authors to characterize the anisotropic material behavior of woven composite fabrics under large deformation,which results from the angle change between warp and weft yarns,was validated by a hemispherical stamping simulation of a square plain woven composite fabric at room temperature.As a comparison,the forming is simulated by using a corresponding orthotropic constitutive model.The simulation results show that the non-orthogonal constitutive... |
