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.
