Learning to Set Up Numerical Optimizations of Engineering Designs

January 1, 1998
Author(s)
Mark Schwabacher, T Ellman, H Hirsh
Gradient-based numerical optimization of complex engineering designs offers the promise of rapidly producing better designs. However, such methods generally assume that the objective function and constraint functions are continuous, smooth, and defined

Measurement Traceability of NIST Standard Rockwell Diamond Indenters

January 1, 1998
Author(s)
Jun-Feng Song, Samuel R. Low III, Walter S. Liggett Jr, David J. Pitchure, Theodore V. Vorburger
A metrology-based Rockwell hardness scale is established by a standard machine and a standard diamond indenter. Both must be established through force and dimensional metrology with acceptably small measurement uncertainties. In 1994, NIST developed a
