WebAug 8, 2024 · It is clear that the fitted curves almost overlap together when the crack orientation is symmetrical at approximately 45°. The sensitive axis of the TMR sensor is … Webof these crack orientation detection schemes are based on ultrasound reflection and scattering. Chang and Mal (1999) investigated the crack orientation by evaluating the time and frequency spectra of Lamb waves scattering around a circular hole with edge cracks. However, quantitative analysis of the crack orientation was not discussed. Lu et ...

Fracture mechanics is a methodology that is used to predict and diagnose failure of a part with an existing crack or flaw. The presence of a crack in a part magnifies the stress in the vicinity of the crack and may result in failure prior to that predicted using traditional strength-of-materials methods. The traditional … See more Cracks act as stress risers and cause the stress in the part to spike near the tip of the crack. As a simple example, consider the case of an … See more There are three primary modes that define the orientation of a crack relative to the loading. A crack can be loaded in one mode exclusively, or … See more A material can resist applied stress intensity up to a certain critical value above which the crack will grow in an unstable manner and failure will occur. This critical stress intensity is the fracture toughnessof the … See more The stress intensity factor is a useful concept for characterizing the stress field near the crack tip. For Mode I loading, the linear-elastic … See more WebThe crystal phase field (PFC) method is used to simulate the propagation of the nano-crack of samples with different crystal orientations under the strain of the uniaxial tensile.
