Definitions of the failure surface, as well as evolution of yield surface are crucial elements in nonlinear FEM analysis of reinforced concrete members and structures carried out with use of elasto-plastic material model. Procedure of formation of these surfaces in MWW3 material model used in author’s computational system Mafem3D has been described. In MWW3 model, each meridian section of yield section...
W artykule krótko omówiono możliwości modelowania efektów termiczno-wilgotnościowo-mechanicznych występujących w betonowych konstrukcjach masywnych. Przedstawiono autorski model fenomenologiczny, który może być wykorzystywany w ocenie ilościowej efektów zachodzących w konstrukcjach masywnych. Omówiono również możliwości rozbudowy modelu w ramach teorii lepkoplastyczności.
