Many practicing engineers have access to multiphysics finite element software 
packages with heat transfer and stress analysis modules and elements. Those packages 
may not, however, include modules formulated for evaluating diffusion problems, so it 
can be difficult for engineers to analyze a concrete structure or component for the effects 
of moisture loss over time. The technique described in this article takes advantage of the 
analogy between the diffusion equation and the heat transfer equation, allowing engineers 
to use commonly-available software tools to analyze concrete structures for stresses 
arising from restrained drying shrinkage. The procedure is a two-step process. After 
establishing the analogy of the diffusion problem with the heat transfer problem, the first 
step is to determine moisture movement in concrete using the heat transfer module of a 
commercial finite element program. In the second step of the process, an empirically-
derived coefficient is used in the stress analysis module of the same program to obtain 
stresses due to constrained shrinkage strains.
