Abstract: Modeling restrained shrinkage induced damage and cracking in concrete is addressed herein. Shrinkage is a volumetric change, considered for now as a mean shrinkage value, provided either by semi-analytical models or by experimental measurements. In the presented study, the novel thick level set (TLS) damage growth and crack propagation model [1-3] is used and adapted by introducing shrinkage contribution into the formulation. The TLS capacity to predict damage evolution, crack initiation and growth triggered by restrained shrinkage in absence of external loads is evaluated. Key results are then compared to experimental results issued from elliptical rings benchmarks found in the literature [4-5]. Ideas for future generalization and enrichment are proposed accordingly.
