Nettet15. sep. 2024 · It was initially designed by Lubliner et al. ( 1989) and later modified by Lee and Fenves ( 1998 ). The definition of a numerical model based on the Plasticity Theory requires the explanation of a flow criterion, the formulation of a constitutive law of hardening/softening and the establishment of a flow law. NettetThe plastic-damage model developed by Lee and Fenves [15] is commonly used for seismic cracking analysis of concrete dams.
