Constitutive Damage Modeling of Concrete in Compression with Dilatation

Abstract

Commencing with "In recent years," the abstract encapsulates the essence of advancements in concrete structure analysis and design. It highlights the shift from traditional methods to more sophisticated numerical analysis techniques, particularly focusing on the development of an anisotropic damage model for concrete within the framework of the internal variable theory of thermodynamics. This model intricately considers the influence of microcracks and microvoids on the material's behavior, offering insights into anisotropic damage and changes in elastic properties. Validated against experimental data and programmed in FORTRAN, the model emerges as a powerful tool for comprehensive structural analysis and design, empowering engineers with a nuanced understanding of concrete behavior under varying loading conditions.
