The composite was a type of strain rate sensitive material. With the increasing of strain ratio, the yield strength of composite increased firstly and then decreased,...
复合材料是应变率敏感的材料，随着应变速率的增加，其屈服强度先增高后降低，而其单位体积吸收的能量则呈上升的趋势。
Because of the lower yield point of rotor material, the local plastic deformations are found during operation at rate speed.
由于转子材料屈服点较低，在额定转速时，局部会出现塑性形变。
The rate of yield and passed products can be increased, and material consumption can be decreased.
优化后产品合格率、成材率提高，原材料消耗降低，并为实现产品结构重大调整奠定了基础。
