In this formulation, a 2D model geometry is used with a single axis of symmetry about which the model is assumedto be 3D through geometric rotation. The installation of the encased column, usually by lateral displacement, was not simulated herein. Plaxis 2D ( Brinkgreve et al., 2012) emphasises the concept of using axisymmetric condition for simulation of cylindrical elements such as soil anchors, nails and piles as shown in Fig. A nonuniform grid with 1726 elements was performed for the calculations - on a 2-dimensional cross-sections of 11m x 3m roadway. The axisymmetric condition uses the x- axis as the radius and y-axis as the symmetrical axis of soil model. It may be observed that the column base was assumed to rest on a rigid stratum. loading application in the PLAXIS 2D uses the Mohr-Coulomb failure criterion in which fully drained and axisymmetric conditions were assumed. #0 Foam::error::printStack(Foam::Ostream&) at ?:? #1 Foam::error::abort() at ?:? #2 Foam::heRhoThermo >, Foam::sensibleEnthalpy>::calculate() at ?:? #3 Foam::heRhoThermo >, Foam::sensibleEnthalpy>::correct() at ?:? #4 ? at ?:? #5 _libc_start_main in "/lib/x86_64-linux-gnu/libc.so. &0183 &32 Finite element analysis using Plaxis 2D with 15 noded element was found to capture the insitu stability condition. &0183 &32 2.3 Phase2:Axisymmetric 2D Numerical Modeling Phase2 also allows computation in axisymmetric mode. &0183 &32 Table 1: Constitutive models and properties adopted in PLAXIS 2D 3.2 Model Description Figure 2a/b shows the axisymmetric model adopted as well as the boundary conditions. > FOAM FATAL ERROR: Maximum number of iterations exceededįrom function Foam::scalar Foam::species::thermo::T(Foam::scalar, Foam::scalar, Foam::scalar, Foam::scalar (Foam::species::thermo::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo::*)(Foam::scalar, Foam::scalar) const, Foam::scalar (Foam::species::thermo::*)(Foam::scalar) const) const in file /home/ubuntu/OpenFOAM/OpenFOAM-4.1/src/thermophysicalModels/specie/lnInclude/thermoI.H at line 66. &0183 &32 ELASTICITY PROBLEMS WITH KNOWN THEORETICAL SOLUTIONS Output: An exact solution to this problem is only available for the case of a Poissons ratio of 0.5 in the PLAXIS calculation a value of 0.495 is used for the Poissons ratio in order to approximate this incompressibility condition.
