Yield Strength
Definition: What is Yield Strength?
A most important calculation in the design of warehouses (both as buildings and as internal structures), yield strength or yield point of a material is defined in engineering and materials science as the stress at which a material begins to deform plastically.
This applies especially to all kinds of beams used in the structure, especially beams that carry any loads or weight. Material used in construction will deform elastically but return to its original shape when the applied stress is removed before it has reached its yield point. Once the yield point is passed, however, some fraction of the deformation will be permanent and irreversible.
Mathematically, yield strength (in materials that do not exhibit a well-defined yield point) equals the stress that produces a specific amount of plastic deformation, usually taken as 0.2 percent of the unstressed length.
In economics, yield is defined as the amount of profit or loss recognized on a company’s investments. The calculation is the amount of income over how much the investment was worth at the start.
