The Uniaxial Compressive Strength of Soft Rock

open access: yesCivil Engineering Dimension, 2007
Soft rock is a term that usually refers to a rock material with a uniaxial compressive strength (UCS) less than 20 MPa. This low strength range might be influenced by physical characteristics, such as size, saturation, weathering and mineral content.

Dynamic compressive strength of silicon carbide under uniaxial compression [PDF]

open access: yesMaterials Science and Engineering: A, 2001
SiC is used in impact related applications, such as integrated armor. This necessitates development of models which describe its dynamic behavior and failure modes. Experimental results, which relate the strain rate to the compressive strength of SiC under uniaxial loading are obtained.
