This report is the first of a continuing study designed to produce more rational tension models for ground shock applications. This document is a review of the state of the art in tensile behavior modeling of earth materials. It contains an historical survey of the field, a discussion of experimental results from various tests and a review of more advanced tensile fracture models, often developed for other applications. In part two of this investigation, it is planned to implement several of the more promising models into the LAYER code to assess their sensitivity and importance for ground shock problems.
