ハンドブックで与えられる板状試験片のK_I,K_IIの精度検討

抄録

Fracture of machines and structures in general is caused by the existence of stress concentration. Therefore, it is important to know the values of stress concentration factor K_t or stress intensity factor K_I, K_II. In many cases, those values can be obtained from stress concentration handbooks. However, the values given in a handbook is not necessarily accurate. So, in this paper, the accuracy of the values of K_I and K_II given in a handbook are examined through the exact values calculated by the versatile program for two-dimensional stress analyses based on the body force method.
