Numerical investigation of forging defects in the hot closed die forging process of cranelifting hooks using FVM and FEM

The production of crane lifting hooks through hot closed die forging is crucial in guaranteeing theirsafety during operation. This article focuses on the design of the forging preform for crane hooks using twodifferent forging methods and simulating them using the finite volume method and the finite element method.The numerical analysis revealed forging defects, including damage and folding in the critical section of the hook,resulting from flattening the initial billet. Additionally, the stress and wear of the dies were examined, and thepreform obtained from bending demonstrated significantly better results compared to the other forgingmethod.
