The purpose of this research was to present a simulation modelling crack propagation trajectory in linear elastic material subjected mixed-mode loadings and investigate the effects existence hole geometrical thickness on fatigue growth life under constant amplitude loading. For various geometry thickness, (I/II) studies were carried out utilize single edge cracked plate with three holes compact...

* Corresponding author; Email: [email protected] ABSTRACT Crack tunneling is a crack growth feature often seen in stable tearing crack growth tests on specimens made of ductile materials and containing through-thickness cracks with initially straight crack fronts. As a specimen is loaded monotonically, the mid-section of the crack front will advance first, which will be followed by crack growth ...

Flaws in material, appearing because of imperfections, manufacturing faults or severe service conditions, can easily threaten the structural integrity of engineering components. This is particularly dangerous when concerning equipment whose purpose is to protect larger systems, e.g. pressure safety valves (PSV) that protect pressure vessels and equipment of overpressure. Catastrophic consequenc...

Article Info ABSTRACT Article history: Received Oct 17, 2016 Revised Dec 4, 2016 Accepted Feb 2, 2017 Nondestructive assessment of cracks in metallic parts has always been a topic of industrial interest. In the past, different approaches have been proposed to assess such cracks. Recently, semi-orthogonal compactly supported spline wavelets were utilized to efficiently identify the 3D spatial lo...
