圆轴拉扭组合大变形的损伤耦合效应

Coupled Damage Effect in a Round-section Axis with Tension and Torsion at Large Deformation

    摘要
  • 摘要: 由Dyson等建立的计算模型,根据塑性损伤演变方程和蠕变损伤演变方程及本构方程推导出圆轴拉扭组合变形问题在大变形条件下的损伤演变方程.

     

    Abstract: The model is proposed based on Dyson model for Nimonie 80A in 1976. The constitutive relationship on the large deformation for a round-section axis with tension and torsion is developed
