estimate of uniaxial compressive strength of the purpose of this study was to clarify the relationships between results of index tests and uniaxial compressive strength (ucs) in hydrothermally altered soft rocks of the upper miocene, which are typical of the soft rock found in northeastern hokkaido, japan. index tests were performed using point load testing machine and needle penetrometer with irregular lump specimens under forceddry

how to calculate compressive strength sciencingcompressive strength involves testing and calculating how well a given specimen, product or material can survive compressive stress. unlike tension, which expands or pulls, compression means a specimen, product or material is shortened or pressed down. compressive strength of a material is the point at which the

compressive strength introductioncompressive strength or compression strength is the capacity of a material or structure to withstand loads tending to reduce size, as opposed to tensile strength, which withstands loads tending to elongate. in other words, compressive strength resists compression (being pushed together), whereas tensile strength resists tension (being pulled apart). in the study of strength of materials, tensile strength, compressive strength, and shear strength can be analyzed independently.
