the stress level at which the pipe will fail/rupture or "break." The ultimate strength of the steel is determined by testing during the manufacture of the pipe.

The tension that a material can with stand without rupturing. Due to their high levels of ductility, most metals have a high value of ultimate strength.

Highest engineering stress developed in material before rupture. Normally, changes in area due to changing load and necking are disregarded in determining ultimate strength.

See "breaking strength".

Is the maximum strength of the member before failure occurs. The symbol Fu is used to denote the ultimate tensile stress.

See Tensile Strength

The greatest load that a portion of material can bear.

Pipelines will break or rupture when they reach the steel reaches or exceeds its ultimate strength level.

A maximum force an object can tolerate before failure.

The maximum resistance to loads that a structure or member is capable of developing before failure occurs, or, with reference to cross sections of members, the largest axial force, shear or moment a structural concrete cross section will support.

Term used to describe the maximum unit stress a material will withstand when subjected to an applied load in a compression, tension, flexural, or shear test.

The maximum strength under which an awning material is capable of sustaining a gradual and uniformly applied load.

Wet Strength Yield Point

measurement that describes the maximum force a metal product can bear prior to failure. The measurement is expressed in a ratio of maximum load to original cross-section area. this is also known as the "tensile strength" measurement.

The maximum stress (tensile. compressive, or shear) a material can sustain without fracture, determined by dividing maximum load by the original cross-sectional area of the specimen. Also called nominal strength or maximum strength.

Maximum strength that can be developed in a material.

As applied to chain, the total tensile force, in pounds, that must be applied to cause failure under stress.
