    Structural analysis of a thermal insulation retainer assembly

    In January 1989 an accident occurred in the National Transonic Facility wind tunnel at NASA Langley Research Center that was believed to be caused by the failure of a thermal insulation retainer. A structural analysis of this retainer assembly was performed in order to understand the possible failure mechanisms. Two loading conditions are important and were considered in the analysis. The first is the centrifugal force due to the fact that this retainer is located on the fan drive shaft. The second loading is a differential temperature between the retainer assembly and the underlying shaft. Geometrically nonlinear analysis is required to predict the stiffness of this component and to account for varying contact regions between various components in the assembly. High, local stresses develop in the band part of the assembly near discontinuities under both the centrifugal and thermal loadings. The presence of an aluminum ring during a portion of the part's operating life was found to increase the stresses in other regions of the band. Under the centrifugal load, high bending stresses develop near the intersection of the band with joints in the assembly. These high bending stresses are believed to be the most likely cause for failure of the assembly

    A and B mortgaged real estate to the plaintiff to secure their notes aggregating 9,000.SixmonthslaterAandBexchangedthispropertytothedefendantforcertainrealestateownedbyher.Bythedeedthedefendantassumedthemortgageindebtednessowedtotheplaintiff.Asafurtherconsiderationfortheexchange,AandBexecutedanotefor9,000. Six months later A and B exchanged this property to the defendant for certain real estate owned by her. By the deed the defendant assumed the mortgage indebtedness owed to the plaintiff. As a further consideration for the exchange, A and B executed a note for 13,050 to the defendant. The plaintiff instituted this action against A and B, seeking to recover the balance, and by amended petition joined the defendant. The defendant claimed the right of set-off on the uncollected judgment against A and B, now insolvent, on the ground that the plaintiff\u27s right was derivative through A and B, and so subject to the same defenses. Held, that the beneficiary\u27s right of recovery against the promisee is subject only to defenses arising from the contract, and therefore is not subject to set-off. Commonwealth Life Ins. Co. v. Eline, 274 Ky. 539, 119 S. W. (2d) 637 (1938)
