Progressive collapse is defined as the spread of an initial failure from element to element, eventually resulting in the collapse of an entire structure or a disproportionately large part of it. The current progressive collapse analyses and design methods in guidelines and codes focus on the alternate load path method. This method is suitable especially in the case of blast-induced progressive ...

In the present study, problems of diffraction and radiation water waves by a cylindrical heaving wave energy converter (WEC) placed in front reflecting V-shaped vertical breakwater are formulated. The idea conceived is based on possible exploitation amplified scattered reflected potentials originating from presence breakwater, towards increasing WEC’s power absorption due to reflections. An ana...

The effects of gap wave resonance on the performance a dual-floater hybrid system consisting an oscillating-buoy type energy converter (WEC) and floating breakwater are important for design such system. This paper investigates by employing two-dimensional numerical flume developed using Star-CCM + software. maximum elevation in WEC-breakwater were studied. influence WEC motion geometrical param...

implantation failure is the most frequent cause of pregnancy loss in couples who try to conceive, either in a natural way or using assisted reproductive techniques (art). identify the precise mechanisms of implantation failure can lead to identify couples at risk and also providing appropriate therapeutic options to affected couples. despite the high prevalence of this disorder, a few causing f...

Due to the extensive use of composites in various industries and the fact that defects reduce ultimate strength and efficiency during operation, detection of failures in composite parts is very important. The aim of this paper is to use Acoustic Emission (AE) non-destructive method in four-point bending test of carbon/epoxy composite to analyze and examine the failure mechanisms. This method is...
