High Capacity Multiaxial Testing Device

Abstract

Abstract In the field conditions, geologic materials are subjected to three-dimensional states of stress. Hence, for appropriate simulation of the field conditions and for deriving constitutive models, it is desirable to test specimens of the materials under truly triaxial states of stress. This paper describes construction, details, and application of a truly triaxial device for testing materials of relatively high strength. A number of improvements over the previous designs are included, and the capability of the device to test a wide range of materials such as ballasts, concrete, rock, and wood is established.
