proportional limit load

См. также в других словарях:

  • limit of proportionality — the stress (load divided by original area of cross section of the test piece) at which the strain (elongation per unit of gauge length) ceases to be proportional to the corresponding stress. It is usually determined from a load elongation diagram …   Mechanics glossary

  • Tangent modulus — In solid mechanics, the tangent modulus is the slope of the compression stress strain curve at any specified stress or strain. Below the proportional limit the tangent modulus is equivalent to Young s modulus. Above the proportional limit the… …   Wikipedia

  • strain — Any deformation or deflection in a body caused by stress. The strain is directly proportional to the stress, as a load is applied until the proportional limit is reached. Beyond that point, the strain may increase at a changing rate until the… …   Aviation dictionary

  • Tensile strength — sigma {UTS}, or S U is the stress at which a material breaks or permanently deforms. Tensile strength is an intensive property and, consequently, does not depend on the size of the test specimen. However, it is dependent on the preparation of the …   Wikipedia
