中心裂纹板双向加载的弹塑性有限元J积分计算
The J-Integral Computation of an Elastic-Plastic Finite Element of the Biaxial Loading in Center Cracked Sheets
【摘要】 本文用弹塑性有限元法计算了中心裂纹板双向加载的J积分。讨论了J积分的路径无关性和裂尖应力,应变奇异性。
【Abstract】 This paper the J-integral computation of biaxial loading in center cracked sheets with elastic-plastic finite element method is given. A path independent of the J-integral and the stress, strain on the crack tip are discussed.
