| This study investigates the effect of thermal residual stress analysis on tetrahedral elements surface structure using finite element technique. An understanding of the effects related to the thermal residual stress is necessary to improve the ability of designers to precisely predict the catastrophic behavior of the apparatuses during overhaul. Tetrahedral elements surface structure production component subjected to applied loads needs to optimize this component that is critical to the tetrahedral elements surface structure efficiency. The applied loads and resulting residual stresses under service conditions is demanded. The finite element modeling was performed. In addition, the fracture life prediction was carried out using finite element based on fatigue analysis. It was observed that the fracture was significantly influenced due to the residual stresses. The obtained result indicates that the existence residual stresses produce the shortest fatigue life for applied loads conditions. The process is one of the promising surface treatments to increase the fracture life for tetrahedral elements surface structure. | ||
