An implicit, elastoplastic, finite element method (FEM) with multi-body treatment function was applied to accurately analyze the real-world shaft clinching of a duplex-pair tapered roller (DPTR) wheel-bearing unit (WBU) under minimal assumptions duri

Mannesmann effect is studied using a hollow cylinder model, which is devised to analyze a hole expansion phenomenon in artificial roll piercing of a hollow cylindrical material by two barrel-type rolls without any mandrel and guiding tools. A rigid-t

In this paper, we present a ring-rolling simulation technique, with emphasis on remeshing capabilities. The technique is based on a dual-mesh approach, in which a finite element analysis model is divided into fine sectors and coarse sectors, and thre

We applied a rigid-viscoplastic finite element method to investigate polygonal-shaped defects that occur during ring rolling and developed an improved analysis model with relatively fine finite elements near the roll gap to reduce the computational t

The material behaviors of two types of bearing steels at hot working conditions are investigated. Stress-strain curves at various temperatures (900–1300°C) and strain rates (1–50/s) are obtained by compression tests with a computer controlled se

In this paper, the stress-strain curves of bearing steels at hot working conditions are obtained by hot compression test with a computer controlled servo-hydraulic Gleeble 3800 testing machine and elongations and reductions of area of the bearing ste
