Safe stress Solution

Follow our step by step solution on how to calculate Safe stress?

FIRST Step Consider the formula

σ w = \frac{σ y}{f s}

Next Step Substitute values of Variables

∴

σ w = \frac{35N/mm²}{2.8}

Next Step Convert Units

∴

σ w = \frac{3.5E+7Pa}{2.8}

Next Step Prepare to Evaluate

∴

σ w = \frac{3.5E+7}{2.8}

Next Step Evaluate

∴

σ w = 12500000Pa

LAST Step Convert to Output's Unit

∴

σ w = 12.5MPa

Variables

Safe Stress

Safe Stress is based on the yield strength of the material and is defined as the yield strength divided by a factor of safety.

Symbol: σ_w

Measurement: PressureUnit: MPa

Note: Value should be greater than 0.

Formulas to find Safe Stress

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.

Symbol: σ_y

Measurement: PressureUnit: N/mm²

Note: Value should be greater than 0.

Formulas to find Yield Strength

Factor of Safety

Factor of Safety expresses how much stronger a system is than it needs to be for an intended load.

Symbol: f_s

Measurement: NAUnit: Unitless

Note: Value should be greater than 0.

Go Engineering strain

𝜀 = \frac{l i - L 0}{L 0}

Go True strain

ϵ T = \ln (\frac{l i}{L 0})

Go True stress

σ T = σ \cdot (1 + 𝜀)

How to Evaluate Safe stress?

Safe stress evaluator uses Safe Stress = Yield Strength/Factor of Safety to evaluate the Safe Stress, Safe stress is based on the yield strength of the material and is defined as the yield strength divided by a factor of safety. Safe Stress is denoted by σ_w symbol.

How to evaluate Safe stress using this online evaluator? To use this online evaluator for Safe stress, enter Yield Strength (σ_y) & Factor of Safety (f_s) and hit the calculate button.

FAQs on Safe stress

What is the formula to find Safe stress?
