About the Von Mises Stress Calculator
The Von Mises Stress Calculator is a free online tool to determine the equivalent (Von Mises) stress from normal and shear stresses under plane stress conditions. It is commonly used in engineering design to assess yielding in ductile materials according to the distortion energy theory.
What You Can Calculate
- Von Mises Equivalent Stress: Evaluate the combined stress for ductile materials under multiaxial loading.
- Stress Assessment: Analyze components under plane stress conditions to check for yielding.
- Unit Conversion: Display results in MPa, kPa, Pa, or psi as needed for design and reporting.
Formula Used
- σv = √(σx² + σy² − σxσy + 3τxy²)
- Where:
- σx = normal stress in x-direction
- σy = normal stress in y-direction
- τxy = shear stress
How to Use the Calculator
- Enter the normal stresses (σx, σy) and shear stress (τxy).
- Select the units for each stress component.
- Choose the desired result unit for the Von Mises stress.
- The calculator will compute the Von Mises equivalent stress and display it in a clear table.
- Use the results to evaluate structural components for ductile material yielding.
Applications of Von Mises Stress
- Mechanical Design: Assess stress in shafts, beams, and machine elements under combined loading.
- Pressure Vessels: Evaluate safety against yielding in tanks, pipes, and cylinders.
- Structural Engineering: Check components in buildings, bridges, and frameworks for ductile failure.
- Material Testing & Research: Compare experimental and theoretical stress values.
- Educational Use: Learn about equivalent stress, plane stress, and distortion energy theory.
