Inferring Mechanical Relaxation Spectra, An Ill-Posed Problem.

Abstract

An effort is made to reduce the number of required mechanical measurements on resin, plastic, and composite specimens. This is achieved by proposing a technique for handling the ill-posed problem of determining a mechanical structural model of a specimen. The results are very encouraging. The report describes in detail the mathematical approach but also presents illustrative graphs comparing assumed mechanical relaxation distributions with those inferred from computer generated experimental data.
