An enhanced damage plasticity model for predicting the cyclic behavior of plain concrete under multiaxial

Mohammad Reza AZADI KAKAVAND, Ertugrul TACIROGLU

Frontiers of Structural and Civil Engineering 2020, Volume 14, Issue 6,   Pages 1531-1544 doi: 10.1007/s11709-020-0675-7

Abstract: Some of the current concrete damage plasticity models in the literature employ a single damage variableThis study presents a cyclic model established by extending an existing monotonic constitutive model.The proposed model, dubbed the enhanced concrete damage plasticity model (ECDPM), is an extension ofan existing model that combines the theories of classical plasticity and continuum damage mechanics.The performance of the model is observed to be satisfactory.
