摘要
文中对中心贯穿、双边、三点弯曲及紧凑拉伸等四类缺口试样进行大量的弹塑性有限元计算表明:通过迭加的方法可以把EPRI全塑性解推广应用到各种分段幂本构关系的材料,从而为这类材料结构中的缺陷评定提供J积分的计算方法。
The numerous Elastic Plastic Finite Element calculations have been carried out for the centre-cracked, double-edge-notched and compact tension specimens, and three-point bend specimens.It is thus shown that the EPRI fully plastic solutions are extended to the material of piecewise-power-law constitutive relationship by means of superposition technique and therefore it provides an approach of J-integral evaluation in defect assessment to this kind of material construction.
