Abstract

Texture has a significant influence on the elastic, plastic, and crack propagation response of crystalline materials. One element of Microstructure Sensitive Design (MSD) [1] is to incorporate texture into the calculation of material properties and to design the material texture such that an optimal material response is obtained. Recent research has placed its focus on generating an interface between the MSD material model and standard computer aided engineering software. The MSD interface (MSDi) would provide to the designer and the design software the needed texture dependent material properties and allow the designer to explore the influence of texture on the performance of the design. The scope of the current paper is to present a case study where such an interface is used with traditional engineering software to optimize the geometric shape and the texture of a cubic material that comprise a turbine disk.Copyright © 2004 by ASME
