Modeling and Crack-growth and Calculate First Intensity Factor with Ansys Software
author
Abstract:
Study about Fracture Mechanics and the root cause of fracture in order to estimates lifetime for Mechanical parts in designing process and manufacturing have tremendous role in this realm. Stress intensity factor comes into design which not only is dependent to geometry also extremely to load condition; for instance, it is important in failure processes (brittle and ductile Materials) or to predict rest life for a mechanical part under fluctuating stress. Stress intensity factor is separated from stress concentration factors. This dimensionless factor, is used to quantify how "concentrated" the stress is. Stress concentration factors are due to geometrical changes of cross sections and regardless of the load condition. At this article, concentrate on modeling and growing a crack during Tension Stress and calculate first stress intensity factor with Ansys software and compare the result with Westgard function

Modeling and simulation of intersonic crack growth
Intersonic crack growth has been studied using an interfacial fracture model in which an additional material phase within a bonding layer is proposed to describe the failure behavior of the interface. In this material phase, a strain gradient based damage model is applied with a built-in cohesive law, which is governed by an material intrinsic length scale that bridges the mechanisms that opera...
full textThreshold stress intensity factor and crack growth rate prediction under mixed-mode loading
A new mixed-mode threshold stress intensity factor is developed using a critical plane-based multiaxial fatigue theory and the Kitagawa diagram. The proposed method is a nominal approach since the fatigue damage is evaluated using remote stresses acting on a cracked component rather than stresses near the crack tip. An equivalent stress intensity factor defined on the critical plane is proposed...

15 صفحه اولa comparison of teachers and supervisors, with respect to teacher efficacy and reflection
supervisors play an undeniable role in training teachers, before starting their professional experience by preparing them, at the initial years of their teaching by checking their work within the proper framework, and later on during their teaching by assessing their progress. but surprisingly, exploring their attributes, professional demands, and qualifications has remained a neglected theme i...
