. The results demonstrate that the MTS criterion evaluated by stress intensity factors (SIFs) can accurately predict the direction of crack propagation in specimens under direct tensile loading. This criterion ...
The Author(s), under exclusive licence to Springer Nature Switzerland AG 2022 Abstract A micro–macro method for evaluating the density of the initial crack . The calculated results the behaviors of direct ...
Abstract An experimental method is proposed for determination of the characteristics of both mode I and mode II cyclic crack resistance of flat specimens for different values of the coefficient ...
. The local stress acting on microcracks in the rock was determined using the micromechanical homogenization method , and a crack initiation stress prediction method considering the interaction between ...
in horizontal stress between adjacent measuring points under the same load step. The development of major crack –horizontal stress –displacement had intrinsic consistency, and the initiation and development ...
characteristics. Four critical strengths of the crack initiation threshold stress , dilatancy boundary stress , short-term strength, and damage ultimate stress of rock salt were determined and then discussed ...
steel. The fracture model calibration is performed in two stages to determine parameters to evaluate : (1) the continuum damage mechanics criterion and (2) ductile crack initiation and propagation ...
that this measurement method can provide the guidance of crack initiation monitoring for magnetic nondestructive testing of coating/substrate interface. Under the effect of applied fatigue loads, high stress ...
state method is simple and can be widely used in engineering. EXTENSION OF THE EQUIVALENT STRESS STATE METHOD TO GENERAL-TYPE CRACK OPENING UDC 539.375 I. M. Pan'ko and N. I. Tim'yak One can determine ...
of components and structural members under cyclic loading, it is necessary to carry out quantitative analysis of stages of both fatigue crack (FC) initiation and its growth. If the methods of evaluating ...
