Compressive strength
Videos
In mechanics, compressive strength is the capacity of a material or structure to withstand loads tending to reduce size. It is opposed to tensile strength, which withstands loads tending to elongate,

Ultimate tensile strength

Ultimate tensile strength is the maximum stress that a material can withstand while being stretched or pulled before breaking. In brittle materials, the ultimate tensile strength is close to the yield
Compressive strength
…strength (or compression strength) is the capacity of a material or structure to withstand loads tending to reduce size (compression). It is opposed to tensile strength, which withstands loads tending to elongate, resisting tension (being pulled apart). In the study of strength of materials, compressive strength, tensile…
Two vises apply tension to a specimen by pulling at it, stretching the specimen until it fractures. The maximum stress it withstands before fracturing is its ultimate tensile strength.
