Micro Abstract:
Shrinkage in cement-based materials can lead to early microcracking. The phenomenon is related to the change of volume at early states, which can lead to cracking if the medium is either internally or externally restrained. Objective of this work is to describe drying shrinkage and autogenous shrinkage in cementitious materials within the framework of poromechanics and phase-field modeling with special focus on crack initiation and evolution. A preliminary calibration of the material parameters is performed in this paper.
