Abstract:
Although many practicing engineers have access to finite element software that can perform heat transfer and stress analyses, this software often doesn’t include modules for evaluating diffusion problems. This can make it difficult 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 diffusion and heat transfer equations to allow commonly available software to analyze concrete structures for stresses arising from restrained drying shrinkage.
