FINITE ELEMENT ANALYSIS OF CONCRETE CRACKING

Critical factors which determine the predictive quality of the finite element analysis of tensile concrete cracking are identified. In particular, two popular methods are explored. These are the smeared crack approach (strength model) and the discrete crack approach (fracture mechanics model). The limitations of these widely accepted strategies are illustrated using the example of a thick walled concrete ring. Extensive strength and deformation data results are obtained.
