Simulated Construction of Spiral Case in a Hydraulic Plant Based on Plastic Damage
Based on the plastic damage model for concrete, this paper realizes the simulated construction for the preloading filling spiral case (PSC) in a hydraulic plant. The contact property and state are analyzed with the nonlinear FEM. The distribution of damage and stress with construction are given. The development mechanism of initial gap is studied. The effect of plastic damage on asymmetry displacement is researched. It is concluded that the influence is remarkable.
