STRAIN IN ROCKS

STRAIN IS DEFINED AS THE ELASTICALLY RECOVERABLE PORTION OF A DEFORMATION. THREE BASIC EQUATIONS ARE PRESENTED WHICH CAN BE COMBINED TO BUILD UP MATHEMATICAL MODELS OF HYPOTHETICAL DEFORMATIONS. THE GENERAL TIME-DEPENDENCY OF THESE SOLUTIONS IS NOTED. STRAIN PATTERNS INDICATE THAT THE DIRECTION OF THE PRINCIPAL STRAIN IS THE DIRECTION OF THE PRINCIPAL STRESS. THEREFORE, USING SUITABLE MEASURING DEVICES SUCH AS PHOTOELASTIC COATINGS, IT IS EASY TO DETERMINE THE STATISTICAL DIRECTIONS OF THE PRINCIPAL STRAINS IN ANY PLANE SURFACE. ENGINEERING CONSIDERATION IN ROCK DESIGN IS ANALYZED.
