rich pocket造句

• The engineering constants around the stitch hole in the composite laminate are analyzed using the fdm . it is found that the elastic constants have distinct region character and the traces of the resin - rich pocket in different lamina are clear
  采用纤维弯曲模型分析了缝纫复合材料单层在缝纫孔附近的最大纤维偏转角、缝纫影响区以及缝纫复合材料单层及层合板工程常数的变化，发现工程常数具有很明显的区域性，能够看出各层中树脂富集区的痕迹。
• The distortion of in - plane fibers is considered to be the main reason for the effect of stitching on the in - plane mechanical properties , and the fiber distortion region , the resin - rich pocket and the through - thickness reinforcement section are taken into account . the fiber misalignment angle and the inhomogeneous fiber volume fraction caused by stitching have been determined within the lamina . the elastic constants of a lamina are calculated using a micromechanical model , then the constitutive equations of the stitched composite laminates can be composed
  从缝纫孔附近纤维变形的细观结构出发，建立的纤维弯曲模型，以面内纤维的弯曲变形作为缝纫影响层合板面内力学性能的主要原因，同时考虑了纤维变形区、厚度增强区以及树脂富集区的影响，得到单向板内任意一点处的纤维偏转角和纤维体积百分含量。
