Abaqus FEA (formerly ABAQUS) is a software suite for finite element analysis and computer-aided engineering, originally released in 1978.The name and logo of this software are based on the abacus calculation tool.The undrained material response of the soil was represented as a linear elastic and perfectly-plastic material, obeying the Tresca criterion. C3D8H, ABAQUS element library) are used in the analyses. First order, fully integration, hybrid hexahedral elements (ref.Abaqus - Tips and Tricks: When to use what Elements? For a 3D stress analysis, ABAQUS offers different typess of linear and quadratic hexahedral elements, a brief description is as below Linear Hexahedral: C3D8 further subdivided as C3D8R, C3D8I, and C3D8H Quadratic Hexahedral: C3D20 further subdivided as C3D20R, C3D20I, and C3D20H, C3D20RH.The node is connected with all the nodes lying To simulate the experimental conditions of applying the load, a dummy node at the top of the isolator is modeled. The hybrid C3D8H element and full integration C3D8 of ABAQUS have been used to model the rubber and steel shims respectively. for each isolator were used in this study.
