Eğilme Altındaki Beton Kirişlerin Çatlak-Bant Genişliği Yaklaşımı ile Boyut Etkisinin Analizi

Abstract

❖ Three-point bending tests are simulated using Concrete damage plasticity model (CDPM) with FEM. ❖ CDPM is enhanced with crack band approach to prevent mesh dependency. ❖ Energy release rate is obtained by using J-integral approach. ❖ CDPM can capture experimental results as well as size effect law of Bazant. ❖ For future study, size effect analysis with CDPM under dynamic loading will be investigated.
