Thermal Stress Microfracturing of Crystalline and Sedimentary Rock: Annual Progress Report.

摘要

The goal of the research program is to understand mechanisms of thermal cracking in granitic rocks. The research plan included development of a theoretical understanding of cracking due to thermal stresses, laboratory work to characterize crack strain in rocks thermally stressed under different conditions (including natural thermal histories), and microscopic work to count and catalog crack occurrences, and geologic application to naturally occurring granites.
