Bolt Stretching and Tensile Stress
Elongation. Bolt stretching according Hook's Law can be calculated as. dl = F L / E A (1) where . dl = change in length of bolt (inches, m) F = applied tensile load (lb, N) L = effective length of bolt where tensile strength is applied (inches, m) E = Young's Modulus of Elasticity (psi, N/m 2) A = tensile stress area of the bolt (square inches, m 2) strain; Stress Area. The tensile stress area ...

3 Common causes of bolt failure | Boltstress Ultrasonics
Boltstress Ultrasonics has eliminated these at several mine sites and mills. Liner bolts fail (break or loosen off) for a number of reasons but the vast majority of these can be eliminated if the preload is correct. Fatigue failure is the most common mode; this is almost invariably due to preload that is too low. This can in turn be divided into 3 groups: inadequate original tension ...
