Equivalent Stress in Principal Stresses Formulas

The Equivalent Stress is the value of uniaxial tensile stress that would produce the same level of distortion energy as the actual stresses involved. And is denoted by σ_e. Equivalent Stress is usually measured using the Newton per Square Meter for Pressure. Note that the value of Equivalent Stress is always negative.

FAQ

What is the Equivalent Stress?

The Equivalent Stress is the value of uniaxial tensile stress that would produce the same level of distortion energy as the actual stresses involved. Equivalent Stress is usually measured using the Newton per Square Meter for Pressure. Note that the value of Equivalent Stress is always negative.

Can the Equivalent Stress be negative?

Yes, the Equivalent Stress, measured in Pressure can be negative.

What unit is used to measure Equivalent Stress?

Equivalent Stress is usually measured using the Newton per Square Meter[N/m²] for Pressure. Pascal[N/m²], Kilopascal[N/m²], Bar[N/m²] are the few other units in which Equivalent Stress can be measured.
