The set of samples used for testing the Lode angle dependency is the same as the one adopted by Li et al.11) and it is composed by: three notched bars, respectively with 6.25, 3.125 and 1.5 mm Webbolted joint is to provide adequate clamping force, joint strength, stiffness and sealing to minimize leakages. Fatigue is one of the critical failure modes in the bolted joint. Bolted joint with preloading minimizes the fatigue damage as the preload reduces the fluctuating stress in the bolt induced by variable external loads.
