Abstract

The previously developed Microplane Concrete Model is improved to expand its applicability and reconstructed into the Enhanced Microplane Concrete Model as a more general constitutive law. One of the main improvements is to take account of resolved lateral stress (resolved lateral component of the macroscopic stress tensor) in normal compression response on the microplane. Another main improvement is to adapt a transition model from brittle to ductile fracture for shear response on the microplane with increasing resolved normal compression stress (resolved normal compression component of the macroscopic stress tensor). Those improvements bring the model a complicated interaction effect between microplanes through macroscopic stress tensor. It is verified that the Enhanced Microplane Concrete Model can predict well experimental constitutive relations of concrete from references.
