摘要
将三维裂纹J积分进行了坐标变换、有限元及高斯积分处理,并借助于Visual Basic 6.0进行了三维裂纹J积分的软件开发,通过实例验证了该软件是合理的。
3-D cracked J-integral formulas was transformed and treated by coordinate transformations,finite element and Gauss integral. 3 D cracked J-integral was developed by VB 6.0 Programming language,and it was verified and was reasonable by virtue of examples.
