Yield Strength vs. Tensile Strength: What's the Difference?

Edited by Sawaira Riaz || By Sumera Saeed || Updated on October 4, 2023
Yield strength refers to the stress at which a material deforms permanently, while tensile strength indicates the maximum stress it can withstand before breaking.

Key Differences

Yield strength is a critical parameter in material science. It denotes the point where a material, when subjected to stress, begins to deform irreversibly. In contrast, tensile strength is the stress level at which materials break or fracture when stretched.

Both yield strength and tensile strength are measures of a material's resistance to mechanical failure, but they signify different behaviors. Yield strength highlights the onset of plastic deformation, while tensile strength signifies the point of outright failure.

Engineers and designers often consider yield strength when determining how a material will respond under load without undergoing permanent deformation. Tensile strength, on the other hand, guides them in understanding the material's overall breaking limit.

In metals, yield strength can often be identified as the point at which the material starts to show significant elongation without additional applied force. Tensile strength is typically where the metal experiences fracture or complete failure.

Materials often have a yield strength that's lower than their tensile strength. This means they'll start deforming at the yield strength, but only break or snap at the tensile strength.
