Abstract

PurposeThe purpose of this paper is to model the strain localization in J2materials with damage evolution using embedded strong discontinuity modes.Design/methodology/approachIn this procedure, an heuristic bandwidth scale is adopted to model the damage evolution in the shear bands. The bifurcation triggering conditions and band growth directions are studied for these materials.FindingsThe resulting formulation does not require a specific mesh refinement to model a localization, provides mesh independent results also insensitive to element distortions and allows calibration of the model response using experimental data. The formulation capability is shown embedding the strong discontinuity modes into quadrilateral and higher order elements.Originality/valueThe work described in this paper extends the use of strong discontinuity modes to materials with damage evolution.
