This paper describes using thermal structural interaction to model the shrinkage behavior in cement paste under drying. An inverse method of combining the finite element analysis and the least-squares method is implemented to fit experimentally determined shrinkage in order to obtain material propertiesfrom the complex geometry used in the tests. The finite element model is created in COMSOL based on thermal-structural interaction with the transient analysis. Results were compared with those from the moiré interferometry experiments to validate the constructed model.
