Residual Bolt Load | Bolt Stress x Bolt Tensile Stress Area (Bolt Stretch x Modulus of Elasticity x Bolt Tensile stress area)/ Effective Length. |
---|---|
Bolt Tensile Stress Area | (3.14 x D X D) / 4 (D is smallest Stress Dia of Bolt) |
% of Yield Strength | (Bolt Stress Required / Yield Strength of bolt) x 100 |
Hydraulic Pressure | (Residual Bolt Load x Load Relaxation Factor) / Hydraulic Area of Load Cell. |
Load Relaxation Factor | 1.01 + (Bolt Size (Dia.) / Effective Length) or 1.1 which ever is greater. |
