COMPLEX VARIABLE FUNCTION SOLUTIONS OF STRESS INTENSITY FACTORS FOR MULTIPLE HOLE-EDGE CRACKS
Jixie qiangdu, 2020 The acceleration effect in the process of collinear hole-edge cracks propagation of aircraft fuselage skin structure is mainly manifested by the interaction of stress intensity factors between multiple fatigue cracks. A modified approximate superposition

Stress-intensity factor equations for cracks in three-dimensional finite bodies [PDF]
Empirical stress intensity factor equations are presented for embedded elliptical cracks, semi-elliptical surface cracks, quarter-elliptical corner cracks, semi-elliptical surface cracks at a hole, and quarter-elliptical corner cracks at a hole in finite

FEBS Open Bio, EarlyView.KHS‐Cnd peptide is able to impair biofilm formation and disaggregate mature biofilms in Acinetobacter baumannii clinical isolates. Differences in extracellular metabolites reflect changes in biofilm metabolism due to KHS‐Cnd treatment. Among the differentially represented extracellular metabolites upon KHS‐Cnd treatment, the significantly altered ...

Two-dimensional fracture analysis of FGM under mechanical loading
Journal of Materials and Engineering Structures, 2020 This paper extends the concept to isotropic functionally graded materials and addresses fracture problems under mechanical loading. The mode-I and mixed mode stress intensity factors (SIFs) are determinate by combination between the finite element method

Improved stress-intensity factors for semi-elliptical surface cracks in finite-thickness plates [PDF]
Stress-intensity factors for shallow and deep semi-elliptical surface cracks in plates subjected to tension are presented. To verify the accuracy of the three-dimensional finite-element models employed, convergence was studied by varying the number of ...

A re-evaluation of finite-element models and stress-intensity factors for surface cracks emanating from stress concentrations [PDF]
A re-evaluation of the 3-D finite-element models and methods used to analyze surface crack at stress concentrations is presented. Previous finite-element models used by Raju and Newman for surface and corner cracks at holes were shown to have ill-shaped ...
