PLAXIS 2012 | Validation & Verification 1Д¬alculations: In the Initial phase zero initial stresses are generated by using the K0procedure ( = 0).

The Expert mesh settings used for the model inPLAXIS 3D are: Meshing: In order to create an extremely coarse mesh, the Very coarse option is usedfor the Global coarseness in PLAXIS 2D. Thedensity and are set to zero, the remaining model parameters are:Д® ref50 = 2.0 104 kN/m2 Eoed = 2.0 104 kN/m2 E refur = 6.0 104 kN/m2 Material: The soil behaviour is modelled by means of the Hardening Soil model. Thepressure 2 is represented by a distributed load on the right plane and 3 is representedby a distributed load on the front plane.ДЇigure 1 Triaxial test - loading conditions The axial load 1 is represented by a distributed load on the top and bottom planes. In PLAXIS 2D the left and the bottom boundaries are fixed inthe horizontal and vertical directions respectively. Theboundary conditions of the geometry are defined as prescribed displacements assignedto the sides of the volume. In PLAXIS 2D an Axisymmetric model is used. Input: A triaxial test is conducted on a geometry displayed in Figure 1 for PLAXIS 2Dand PLAXIS 3D respectively. The probleminvolves axial loading under triaxial test conditions. This document describes an example that has been used to verify the elasto-plasticdeformation capabilities according to the Hardening Soil model of PLAXIS.
