UPCOMING LIVE WEBINAR
Refine your Mesh
Strain-softening materials, such as concrete, make a standard finite element model mesh-dependent: as the mesh is refined, the localization band narrows, the dissipated energy decreases, and the computed response does not converge. This webinar reviews the problem and the techniques used to recover mesh-objective results.
