Elastic Degradation and Damage in Concrete following Nonlinear Equations and Loading Function

摘要

In the present work an elastic-degrading model is used in the analysis of concreternunder three dimension states of stress. The non-linear behaviour is controlled by thernequation defined in the CEB-FIP Model Code 1990 for axial compression. Therninitiation of damage in three dimension states of stress is controlled by the use of thernVon Mises or the Drucker-Prager criteria.
