Abstract: Systems and methods for designing oxide ceramic matrix composite parts entail creating a simulation of the oxide ceramic matrix composite part based on expected processing parameters to be used to create the oxide ceramic matrix composite part as well as material characteristics of one or more materials to be used to create the part. The part so created is subjected to simulated structural testing to predict performance of a potential physical counterpart, and the physical counterpart of the simulated oxide ceramic matrix composite part is then produced if the simulated testing yields results that conform to predetermined performance requirements.

Abstract: A structure includes a nanophase titanium node and a plurality of nanophase aluminum struts. Each of the plurality of nanophase aluminum struts is bonded to the nanophase titanium node at a weld joint.

Abstract: The novel concept to be patented involves minutely indenting the standard fasteners along the pitch line at various points and utilizing the small material deformations around these indentations to provide substantial engagement to resist loosening of the joint under operational loads. The basic idea is to stamp a typical pattern (two are described below) on the fastener to achieve the advantages of a self-locking mechanism as well as enhance the torque and load carrying capability of the joint. Moreover, the indentations being in the order of few mils would not degrade the strength of the fastener, but would continue to provide sufficient load transfer across the joint without loss of preload. Furthermore, the joint can be disassembled and the fasteners can then be reused for the subsequent operations. These unique indentations on the fasteners can be of varying numbers, depths, geometry (spherical, elliptical etc.) and of various patterns (linear, staggered etc.
