A Scanning Electron Microscope Investigation of Statically Loaded Foundation Materials.
Abstract
Selected rock samples were prepared and tested to failure in bending, tension, and compression test modes within the vacuum stage of a scanning electron microscope. The load was applied very slowly so that crack initiation and growth could be observed. The latter was observed visually and was recorded by both photography and video tape. The cracked surfaces of the failed specimens were further evaluated by more standard methods; two evaluation techniques were used to determine the failure the mechanisms involved for each test mode and rock type studied.
