Yield Strength in Mechanical Behaviour and Testing Formulas

Yield strength can be defined as follows, a straight line is constructed parallel to elastic portion of stress–strain curve at strain offset of 0.002. And is denoted by σ_y. Yield Strength is usually measured using the Newton per Square Millimeter for Pressure. Note that the value of Yield Strength is always positive.

FAQ

What is the Yield Strength?

Yield strength can be defined as follows, a straight line is constructed parallel to elastic portion of stress–strain curve at strain offset of 0.002. Yield Strength is usually measured using the Newton per Square Millimeter for Pressure. Note that the value of Yield Strength is always positive.

Can the Yield Strength be negative?

No, the Yield Strength, measured in Pressure cannot be negative.

What unit is used to measure Yield Strength?

Yield Strength is usually measured using the Newton per Square Millimeter[N/mm²] for Pressure. Pascal[N/mm²], Kilopascal[N/mm²], Bar[N/mm²] are the few other units in which Yield Strength can be measured.
