We provide numerical simulations of concrete-dam response to dynamic loading (such as earthquake ground motions), showing the location and three-dimensional geometry of potential cracks or fractures. The simulations model fracture initiation and propagation using our innovative fracture-propagation modeling. The following plots describe an example.
blue = unfractured, orange = one tensile fracture, and red = two fractures (tensile and shear). [From Ofoegbu GI and B Dasgupta (2021).
