The service life of the oilfield wire rope can be greatly extended by using sheaves made of material with low elastic modulus.
石油矿场机械设备用于支承钢丝绳的钢制绳轮，采用低弹性模量的材料制作，可大幅度地延长钢丝绳的使用寿命。
Temperature impacted on the fracture stress and elastic modulus of the material obviously. Elevated temperature will lead to low fracture stress and smaller elastic modulus.
温度对断裂应力和弹性模量的影响也比较明显，高温会导致低的断裂应力和小的弹性模量。
