Coupled Damage Effect in a Round-section Axis with Tension and Torsion at Large Deformation
-
摘要: 由Dyson等建立的計算模型,根據塑性損傷演變方程和蠕變損傷演變方程及本構方程推導出圓軸拉扭組合變形問題在大變形條件下的損傷演變方程.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
