| 摘 要： | 损伤因子D和损伤应变能释放率Y是损伤力学中的两个重要参量。本文将Lemaitre的应变等价性假设应用于纯剪切的情况,导出了D和Y的相应表达式,以此作为用薄壁圆筒扭转测D和Y的理论依据。文中以35号钢为材料,测出其相应的Dc和Yc。

| Abstract: | The damage factor D and the release rate of damage strain energy Y are two important parameters in Damage Mechanics.At present In this paper,according to Lemaitre's strain equivalent hypotesis and applying it to the pure shearing case;we derived the corresponding expressions of D and Y,and use them as a theoretical basis for measuring D and Y through a thin-walled cylinder torsion test.Here 35 steel was used and its corresponding values of DC and Yc were found. |
