Maximum Shear Stress from Von Mises Criterion Solution

Follow our step by step solution on how to calculate Maximum Shear Stress from Von Mises Criterion?

FIRST Step Consider the formula

𝜏 max = 0.577 \cdot σ y

Next Step Substitute values of Variables

∴

𝜏 max = 0.577 \cdot 35N/mm²

Next Step Convert Units

∴

𝜏 max = 0.577 \cdot 3.5E+7Pa

Next Step Prepare to Evaluate

∴

𝜏 max = 0.577 \cdot 3.5E+7

Next Step Evaluate

∴

𝜏 max = 20195000Pa

LAST Step Convert to Output's Unit

∴

𝜏 max = 20.195MPa
