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,...
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。

At the same time it is helpful to yield increasing, material consuming reduction, the reduction of the rate of defective products and the improving of operation rate of equipment.
