| Abstract: | With the aid of FEM analysis software, the simulative calculation on one water-stop rubber is proposed, which is considered as one kind of hyperelastic, incompressible materal with large deformation. Taken the problem as a physically and geometrically nonlinear one, the large deformation states are analyzed. Moreover, the rubber branch head stress distribution and contact stress distribution between rubber and steel plate of water-stop rubber installation are investigated. |
