Drying Shrinkage

    Drying results in capillary pressure that causes shrinkage. If significant contraction occurs, the stiffness of the body generally increases. Given knowledge of the capillary pressure and the mechanical properties of the solid phase, the final shrinkage of the body can be predicted. The following papers provide the theoretical framework and experimental verification of the predictions.

    Papers that deal with supercritical drying, and drying stresses are listed separately.
