Average Shear Stress vs Shear Force (V)
Fórmula
## Average Shear Stress Shear stress arises from forces acting parallel to a cross-section. ### Formula **tau_avg = V / A** where V is the internal shear force and A is the cross-sectional area resisting the shear. For beams, the actual shear stress distribution is parabolic (maximum at the neutral axis), and the peak value for a rectangle is 1.5 times the average.
Ejemplo Resuelto
A steel plate connection with 3000 mm^2 shear area carries 50 kN.
- 01Convert force: 50 kN = 50,000 N
- 02tau = 50,000 / 3,000 = 16.67 MPa
Preguntas Frecuentes
How does shear stress differ from bending stress?
Bending stress acts perpendicular to the cross-section (normal stress) and varies linearly from the neutral axis. Shear stress acts parallel to the section and varies parabolically, peaking at the neutral axis.
What is the maximum shear stress in a rectangular beam?
The peak shear stress in a rectangular cross-section is tau_max = 1.5 V / A, occurring at the neutral axis. This calculator gives the average value V/A.
What is a typical shear yield strength?
Shear yield is approximately 0.577 times the tensile yield strength (von Mises criterion). For A36 steel with 250 MPa tensile yield, shear yield is about 144 MPa.
