本文推导了抗拉、抗压模量不同材料的球孔扩张时的应力及位移的计算公式,并运用所推导的公式分析了材料的拉压模量不同时对球孔扩张时的应力、位移及塑性区开展规律的影响,并得出了一些有益的结论。
This paper deduces the calculation formulas for the stress and displacement when the ball holes of different materials with different tensile and compressive moduli are expanded, and uses the derived formula to analyze the stress and displacement when the tension and compression moduli of the materials are different when the holes are expanded. And the plastic zone developed the influence of the law and reached some useful conclusions.
