A single pulse is transmitted .
Sometimes, testing of cohesive samples is done with no confining pressure, in an unconfined compression test. This requires much simpler and less expensive apparatus and sample preparation, though the applicability is limited to samples that the sides won't crumble when exposed, and the confining stress being lower than the in-situ stress gives .

[1] This test indirectly measures the tensile property of a material object, as the molecules of the material are pushed apart in opposite directions, similar to what happens to molecules in a direct tensile strength test.
The ultimate tensile strength of a material is an intensive property; therefore its value does not depend on the size of the test specimen.However, depending on the material, it may be dependent on other factors, such as the preparation of the specimen, the presence or otherwise of surface defects, and the temperature of the test environment and material.In engineering and materials science, a stress–strain curve for a material gives the relationship between stress and strain.It is obtained by gradually applying load to a test coupon and measuring the deformation, from which the stress and strain can be determined (see tensile testing).These curves reveal many of the properties of a material, such as the Young's .A representative pressure–volume diagram for a refrigeration cycle.
