Tensile strength is the stress at the maximum on the stress-strain curve.
The greatest longitudinal or axial stress a material can bear without breaking.
Tensile strength is the maximum amount of tensile stress that a material can take before failure. There are three definitions of tensile strength
- Yield strength
- Ultimate strength
- Breaking strength
The stress at which material strain changes from elastic deformation to plastic deformation, causing it to deform permanently. This point is not a well defined point. We can say that yield strength is a strength which a material can bear without permanent deformation.
Yield strength of Structural steel A36 is 250 MPa.
The maximum stress a material can withstand. Ultimate tensile strength of Structural steel A36 is 400 MPa.
The stress coordinate on the stress-strain curve at the point of rupture.
