Based on observing and analyzing digital images and microstructure of 3D woven composites cross-sections,the results show that the position of deciding the thickness of 3D woven composites is located at the cross-section which passes through the center of the weft thread,the cross-section of a warp thread is rectangular,and the longitudi.

Finite element simulation of material flow and section formation in sheet metal blanking

The effect of the variation of the translational velocity on the material flow and the equivalent plastic strain are also studied.

The influence law of loading conditions, such as loading area, transitional area and outside restriction, on the material flow and filling during forming process was explored, based on the rigid-viscoplastic finite.
