Equations edit
- For average shear stress
- where
- is the average shear stress,
- is the shear force applied to each section of the part, and
- is the area of the section.[1]
- Average shear stress can also be defined as the total force of as
- [2]
- Practically, the equations only give an approximation. Stress is not often equally distributed across a part so the shear strength would need to be higher to count for the estimate along with a factor of safety.
Comparisons edit
There are no published standard values for shear strength like with tensile and yield strength. Instead, it is common for it to be estimated as 60% of the ultimate tensile strength. Shear strength can be measures by a torsion test where it is equal to there torsional strength.[3][4]
