Influence of notch parameters on fracture behavior of notched component
In the present study, the influence of variation of notch parameters on the notch stress intensity factor KI is studied using CTspecimen made from steel construction. A semi-elliptical notch has been modeled and investigated and is applied to finite elements model. The specimen is subjected to a uniform uniaxial tensile loading at its two ends under perfect elastic-plastic behavior. The volume...
متن کاملModeling Underwater Structures
Deliberate exploitation of natural resources and excessive use of environmentally abhorrent materials have resulted in environmental disruptions threatening the life support systems. A human centric approach of development has already damaged nature to a large extent. This has attracted the attention of environmental specialists and policy makers. It has also led to discussions at various natio...
متن کاملReinterpretation of Karihaloo’s size effect analysis for notched quasibrittle structures
Karihaloo recently published an analytical study of the size effect in concrete based on large-size asymptotic approximations of the cohesive crack model. From this analysis, he concluded that the nominal strength can be determined only for sizes above a certain lower bound, large enough to invalidate, at least for concrete, all the existing experimental methods based on size effect measurement...
متن کاملinvestigating the ancient siraf’s coastal architectural structures by underwater archaeology
some researchers believe that because of the severe earthquake and tsunami in the fourth century h., a large part of siraf submerged by the persian gulf water fluctuations. based on the available evidence and also by the archaeological survey of the siraf coastal surrounding areas, the author argues that despite the devastating earthquake occurred to destroy much of the coastal architectural st...
متن کاملProfile Following for Inspection of Underwater Structures
We present a seabed profile estimation and following method for close proximity inspection of 3D underwater structures using autonomous underwater vehicles (AUVs). The presented method is used to determine a path allowing the AUV to pass its sensors over all points of the target structure, which is known as coverage path planning. Our profile following method goes beyond traditional seabed foll...
