Shear Stress Calculator

Your details

Direct shear: a force sliding parallel to a surface. Torsional: a shaft twisted by a torque. Transverse: a beam loaded transversely - stress varies over the cross-section depth.
The force acting parallel to the cross-sectional area (shear plane).
N
Cross-sectional area resisting the shear force.
mm²
Material allowable shear stress. When non-zero, a factor of safety is calculated. Leave at 0 to skip.
MPa
Shear stress (tau)
25

Calculated shear stress at the specified location.

UnitMPa

Shear stress is 25.000 MPa (direct shear).

  • Direct shear stress is uniformly distributed across the shear plane in simple theory, making this formula conservative and widely used for fasteners, pins, and welds.
  • This stress level is below the typical shear yield strength of structural steels (around 100 to 200 MPa), which suggests adequate capacity for most metal components.

Next stepEnter an allowable shear stress above to compute the factor of safety and confirm the design is adequate.
