предел прочности при растяжении(Ultimate tensile strength (UTS), often shortened to tensile strength (TS) or ultimate strength,[1][2] is the maximum stress that a material can withstand before necking, which is when the specimen's cross-section starts to significantly contract.

испытание на одноосное сжатие(глоссарий Schlumberger: "A measure of a material's strength. The unconfined compressive strength (UCS) is the maximum axial compressive stress that a right-cylindrical sample of material can withstand under unconfined conditions–the confining stress is zero. It is also known as the uniaxial compressive strength of a material because the application of compressive stress is only along one axis–the longitudinal axis–of the sample" slb.comО. Шишкова)
