基于J2-积分与六棱柱壳裂纹应力强度因子
The Stress Intensity Factor of Six Prismatic Cracked Shell Based on J2-Integral
摘要
Abstract
As one of the important fracture parameters, stress intensity factor plays an important role in the fracture analysis of engineering structures.Based on the concept of J2-integral and the elementary theory of strength of materials,the stress intensity factors of the transverse crack of the six prismatic shell and the six prismatic shell with reinforcing rib are analyzed and solved.A method for solving the stress intensity factor of complex structure by using J2-integral method is presented.关键词
