Study of shrinkage stresses for drying of brick as a conjugate problem. (English) Zbl 0977.74018

Summary: We study numerically the drying-induced shrinkage stress of a two-dimensional rectangular brick of aspect ratio 2. The drying of brick is analyzed as a conjugate problem. The conservation equations for the solid are obtained using continuum approach, and Navier-Stokes equations are solved for the flow field. An elastic model is used to calculate the shrinkage stresses. The present unified model predicts the stress concentration at the leading edge, where it is expected to be maximum due to large shrinkage.
