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。
