Yield Strength vs. Tensile Strength: Know the Difference
By Shumaila Saeed || Updated on December 25, 2023
Yield Strength is the stress at which a material begins to deform plastically, while Tensile Strength is the maximum stress a material can withstand while being stretched or pulled.
Key Differences
Yield Strength refers to the point on the stress-strain curve where a material transitions from elastic deformation to plastic deformation, indicating the limit of reversible deformation. Tensile Strength, on the other hand, represents the maximum stress that a material can bear while being stretched before breaking, showing the material's resistance to breakage under tension.

In testing, Yield Strength is identified by the stress level at which a material undergoes a permanent deformation of 0.2%, while Tensile Strength is determined at the point of fracture. Yield Strength is crucial for determining a material's ability to handle certain loads without permanently deforming, whereas Tensile Strength is essential for understanding how much stress a material can withstand before it fails.

Yield Strength is a critical property for materials that will undergo loads leading to temporary deformation, as it indicates the maximum stress that can be applied without causing permanent changes. Tensile Strength is paramount in applications where materials are subjected to stretching forces, as it measures the ultimate strength of the material when pulled.

Materials with high Yield Strength can endure higher stresses without permanent deformation, making them ideal for structural applications. Materials with high Tensile Strength can withstand greater stretching forces before breaking, which is crucial in applications like cables and ropes.

In summary, Yield Strength is about the threshold beyond which a material will not return to its original shape, while Tensile Strength concerns the extreme limit of strength a material has under tension before it ruptures.
