Adam's Green's Function Library Space

On October 15-16, 1999, the NIST CTCMS held a workshop on the "Green's Function Library" technique.  The essence of the technique is that when a boundary element mesh is divided into two surfaces S1 and S2, typically one complex and one simple, the inverted Green's function matrix for the complex matrix A11-1 can be used to solve problems for multiple configurations of S2 very quickly.  A set of A11-1 matrices would constitute a library of available Green's functions for the complex surfaces, which can be saved for use with various simple S2 surfaces.  Feel free to peruse the Workshop Summary, which includes the theory behind this technique.

Adam Powell quickly realized that there are numerous potential Materials Science applications of this technique.  In addition to a couple of potential solder applications, one can use S2 to describe a defect, such as a void or inclusions.  Then one can look at the effect of not merely the effect of location of a single defect on mechanical behavior, but very efficiently scope out the space of distributions of multiple defects, with various sizes and shapes!
