    • ALE formulation and its application in solid mechanics 

      Gadala, Mohamed S.; Wang, J. (Science Direct, 1999-03)
      In this paper an incremental approach is used to derive an arbitrarily-Lagrangian-Eulerian (ALE) finite element formulation including a complete expression of the external virtual work. The characteristics of this formulation ...

    • Computational implementation of stress integration in FE analysis of elasto-plastic large deformation problems 

      Wang, J.; Gadala, Mohamed S. (Science Direct, 2000-06)
      In this paper, we compare different numerical implementation algorithms for the rate type constitutive equation and present an integration scheme based on the physical meaning of the stress. Numerical implementation of ...

    • Formulation and survey of ALE method in nonlinear solid mechanics 

      Wang, J.; Gadala, Mohamed S. (Science Direct, 1999-12)
      This paper investigates the applicability and accuracy of existing formulation methods in general purpose finite element programs to the finite strain deformation problems. The basic shortcomings in using such programs in ...

    • On the mesh motion for ALE modeling of metal forming processes 

      Gadala, Mohamed S.; Movahhedy, M.R.; Wang, J. (Science Direct, 2002-01)
      Arbitrary Lagrangian–Eulerian finite element method is being increasingly used for simulation of metal-forming operations, due to its capability to combine the features of both Lagrangian and Eulerian approaches in a single ...

    • Simulation of metal forming processes with finite element methods 

      Wang, J.; Gadala, Mohamed S. (Wiley Online Library, 1999-03)
      The traditional Lagrangian and Eulerian formulations in finite elements posses some inherent difficulties when used in simulation of metal-forming processes or general finite strain problems. A more general method of ...
