Crack Group Effect Analysis of the Stress-Release Boot of.

Due to the complex process of the insulation layer patch in solid rocket motor SRM, only manual patch could be used. Sometimes weak bonding or debonding in each joint surface was inevitable. This study is aimed at determining the crack group effect of insulation and interfacial debonded crack in the wide-temperature SRM. The crack group appeared in the front area of the ahead stress-release.

We show that the effect of the crack depends on the strain energy loss, which actually is proportional to the curvature achieved by the affected region in the radial direction.Hamat Codruta Oana, Praisach Zeno-Iosif, Barbinta Constantin-Ioan, Korka Zoltan-Iosif, Gillich Gilbert-Rainer Circular crack identification in plates based on natural frequency evaluation. Three types of cracks are considered herein to demonstrate this dependency, differing by their length. It consists in analyzing and interpreting the frequency changes that occur due to a circular arc crack. We propose in this paper a method to detect cracks in circular plates clamped at the circumference.Modal analysis is performed involving a professional simulation software for the intact plate, and that with the generated cracks.In most of civil engineering projects from Housing to hydraulic related projects hydrology is mostly involved in combination with fluid mechanics.Water distribution networks are of significance importance from satisfaction of end user point of view.
