Gradient‐based refinement indicators in adaptive finite element analysis with special reference to sheet metal forming
Ramin Moshfegh, Xiangdong Li, Larsgunnar NilssonTwo mesh refinement indicators based on the gradients of effective stress (GSIG) and effective plastic strain (GEPS), respectively, are proposed for adaptive finite…
An implementation of mixed enhanced finite elements with strains assumed in Cartesian and natural element coordinates using sparse B (overline)‐matrices
R. PiltnerThe use of enhanced strains leads to an improved performance of low order finite elements. A modified Hu‐Washizu variational formulation with orthogonal stress and strain…
A quadrilateral mesh generator for adaptive procedures in bulk forming processes
R.M. Natal Jorge, Rui P.R. Cardoso, J.M.A. César de SáThe simulation of real industry metal forming processes often requires the presence of adaptive procedures. With that purpose a quadrilateral mesh generator was developed…
A hybrid formulation in the stress analysis of curved pipes
Luísa Madureira, Francisco Q. MeloDescribes a hybrid formulation solution based on variational techniques, where unknown functions are combined with a set of Fourier trigonometric expansions. The unknown…
An empirical comparison of three novel genetic algorithms
Hui‐Yuan Fan, Jane Wei‐Zhen Lu, Zong‐Ben XuGenetic algorithms have been extensively used in different domains as a type of robust optimization method. They have a much better chance of achieving global optima than…
