Computational Seismic Fracture Synthesis of Tidal Barrage using Enhanced Isotropic Plasticity Damage Mechanics and Coupled Lagrangian-Eulerian Multiphase Interaction (2403.10905v1)

Published 16 Mar 2024 in physics.flu-dyn, cs.NA, math.DS, and math.NA

Abstract: Mega-engineered hydraulic structures like dams and barrages are critically sensitive to strong ground motion if constructed within the vicinity of triggered fault lines. Collapse post excessive deformation leads to severe environmental impact. In this study, fracture corresponding to the response of a concrete tidal barrage to strong ground motion is analyzed along with behavioral effects due to reservoir-barrage dynamic interaction. An enhanced version of the plasticity damage mechanical model, which includes effects due to degradation of elastic stiffness of concrete as well as restoration of fracture energy losses is assigned as material behavior. The fluid-structure interaction is solved using an idealized Lagrangian-Eulerian formulation. The proposed improvised numerical formulations are validated against benchmark simulations performed on the Koyna dam situated in Maharashtra, India and the results captured are upto 94% accurate. Finite element simulation of a tidal barrage is performed using a computationally stable mesh with global grid to length ratio of 4.2. The yield surface captured is elliptical in nature and fracture is observed to be propagating from bottom of gate housing covering upto four nodal integration points.
