Abstract:
In this paper, the relationship between a discontinuity’s edge angle and magnetic leakage signal is investigated to provide a new reference basis for discontinuity reconstruction and to improve its accuracy. The magnetic leakage signals of V-shaped, rectangular, and right-angle trapezoidal discontinuities with different edge angles (i.e., the angle between the discontinuity boundary and the horizontal direction) are studied through COMSOL simulations and experiments. The regression equations for both are established, and the findings are summarized. The results show that as the edge angle incr

Abstract:
The discontinuity’s surface topography is often assumed as smooth and straight. To overcome non-considering roughness of discontinuity, direct shear numerical experiment is proposed to research influences of discontinuous roughness on its strength. Firstly, based on researched mechanical properties of discontinuity, the laws how asperity inclination angles and asperity heights of discontinuity and the mechanical behavior of discontinuity are studied. The results show that the failure of discontinuity considering roughness is not instantaneous. It is a complex process which goes through energy

Abstract:
Purpose Determining fiber orientations around geometric discontinuities is challenging and simultaneously crucial when designing laminates against failure. The purpose of this paper is to present an approach for selecting the fiber orientations in the vicinity of a geometric discontinuity; more specifically round holes with edge cracks. Maximum stresses in the discontinuity region are calculated using Classical Lamination Theory (CLT) and the stress concentration factor for the aforementioned condition. The minimum moment to cause failure in a lamina is estimated using the Tsai–Hill and Tsai–W

Abstract:
Non-linear schemes are widely used in high-speed flows to capture the discontinuities present in the solution. Limiters and weighted essentially non-oscillatory schemes (WENO) are the most common non-linear numerical schemes. Most of the high-resolution schemes use the piecewise parabolic reconstruction (PPR) technique for their robustness. However, it may be impossible to achieve non-oscillatory and dissipation-free solutions with the PPR technique without non-linear switches. Most of the shock-capturing schemes use excessive dissipation to suppress the oscillations present in the discontinui
