Abstract
Finite element computations with the smeared approach give rise to mesh dependence when strain localization occurs. The inelastic process localizes in a narrow region of the structure diminishing to zero with further mesh refinement. The total energy disspication vanishes and a full snap back of the solution is recovered when a mixed force/displacement control is provided. Regularization of a scalar damage constitutive description is introduced for obtaining objectivity of the results with mesh refinement of a plane strain concrete panel in axial extension.| File | Dimensione del file | Formato | |
