A crack normal to and terminating at a bimaterial interface
TL;DR: In this paper, the authors investigated the plane problem of a crack normal to and terminating at a bimaterial interface and derived the singular stress field at the crack tip that touches the interface.

Analysis of singular stress field around the inclusion corner tip
TL;DR: In this article, the singular stress field around the inclusion corner tip is expressed as a sum of two independent types: a symmetric type with a stress singularity 1 r 1−λ1 and a skew-symmetric Type I, 1 −λ2.

Singular Stress Fields near the Tip of a V-Notch in a Semi-Infinite Plate
TL;DR: In this paper, a new method is presented for analyzing the problem of the V-notch in a semi-infinite plate, in which the two singular stress fields are taken into account at the same time, and the parameters KIλ1 and KII, λ2 are determined by the solutions of the equations.

Detection of a crack by body force method
Chen Dai-Heng,Nisitani Hironobu +1 more
TL;DR: In this paper, a new practical method is proposed to determine the location and the size of a crack and the loading stresses based on the data of measured strains in the structure, where the unknown parameters are determined by the condition which minimizes an objective function.

Analysis of the delaying effects of overloads on fatigue crack propagation
Chen Dai-Heng,Nisitani Hironobu +1 more
TL;DR: In this article, a simulation analysis of fatigue crack propagation was carried out in order to investigate the delaying effects of overload on fatigue crack propagating, and the results of simulation analysis were compared with the experimental data obtained by other researchers.
