dc.descriptionAbstract: Minimizing thermal cracking in mass concrete continues to be a concern for the US Army Corps of Engineers. Thermal cracking is due to the restraint of volume change due to hydration, shrinkage, and creep. The prediction of stresses, strains, and cracking at early times presents special problems because many of the properties of concrete depend on the degree of hydration of the cementitious materials. To better model the time-dependent properties and response of mass concrete, a time-dependent cracking material model was developed for use in a general-purpose heat-transfer and structural analysis finite element code. The model includes the effects of time and temperature on compressive strength, elastic modulus, and creep. An interactive strain-driven, stress-modified cracking criterion based on the smeared-crack approach is included. Examples of calibration and verification of the model are included.-
