由虚功原理推导J积分守恒
The Derivation of J-lntegral Conservation Law from the Principle of Virtual Work
-
摘要: 本文由力学的普遍原理——虚功原理推导出了三维情况下J积分守恒的一般形式;十分明显地给出了J积分守恒成立的几个必要条件.Abstract: The general form of J-integral conservation law in three dimensions has been derived from the principle of virtual work. The necessary conditions for J-integral conservation are also given.
