Finite element simulation of non‐linear transient response due to rotor‐stator contact

S.L. Chen, M. Géradin

The non‐linear dynamics due to rotor‐stator contact is simulated using the finite element method. Develops and describes a general contact finite element. By implementing…

An adaptive meshing automatic scheme based on the strain energy density function

A. Hernández, J. Albizuri, M.B.G. Ajuria, M.V. Hormaza

Proposes an automatic adaptive meshing scheme. Error in strain energy is directly obtained through strain energy density function (SED). Versatility of this function, in…

Tooling mesh generation technique for iterative FEM die surface design algorithm to compensate for springback in sheetmetal stamping

Longwu Wu

FEM analysis has been increasingly employed to simulate sheetmetal forming processes for industrial application purposes. From the simulation results, finite element…

Investigation into non‐steady‐state three‐dimensional helical extrusion of twisted sections by the rigid‐plastic finite element method

Y.B. Park, D.Y. Yang

In metal forming, there are problems with recurrent geometric characteristics and without explicitly prescribed boundary conditions. In such problems, so‐called recurrent…

Implementation and application of elastodynamic boundary element discretizations with improved stability properties

E. Siebrits, A.P. Peirce

Direct and indirect time marching boundary element methods often become numerically unstable. Evidence of, and reasons for, these instabilities is provided in this paper…
