- Abstract
- An education module demonstrating the principles of computational materials science has been developed. The module consists of: software that executes on a personal computer, and this NIST Technical Note, which provides documentation and instructions for using the computer software. The computer programs are availabe for both DOS-compatible PC and Macintosh computing environments. Four separate computer programs illustrate the development of microstructure during cement hydration, mercury intrusion porosimetry, percolation of overlapping ellipses and rectangles as a function of aspect ratio, and percolation of non-overlapping hard cores each encompassed by a soft overlapping shell. All of the programs operate on two-dimensional microstructures due to the space and time limitations imposed by a personal computer environment. The computer software is interactive and highly graphics-oriented. To date a preliminary version of the computer module has been utilized in a variety of undergraduate and graduate level civil engineering classes. Feedback from faculty and students has been used to revise and enhance the capabilities of the computer program.
