PLAXIS 2D 2011

Description

Plaxis is a finite element program for plane strain and axisymmetric modelling of soil and rock behaviour. Fully automatic mesh generation, allowing for a virtually infinite number of 6-node and 15-node elements, based on graphical input of soil layers. Elements exist to model walls, plates, anchors, geotextiles and soil-structure interaction. A special tunnel designer exists to create circular and NATM-like tunnels including lining and interface. Ground loss during tunnelling can be simulated. Fully automatic load stepping procedure. Staged construction enables realistic simulation of the construction process. Soil models: Linear elastic, Mohr-Coulomb, Soft-Soil model (Cam-Clay like), Soft-Soil Creep model (Cam-Clay like with time-dependent behaviour), Hardening Soil model (double hardening). Models can contain both drained and undrained layers. For undrained layers excess pore pressures are calculated and elastoplastic consolidation analysis may be carried out. Steady pore pressures may be generated by input of phreatic lines or by groundwater flow analysis. Large deformations may be analysed by means of an Updated Mesh (Lagrangian) calculation. Factor of safety calculation by means of phi-c-reduction. Fully graphical input and output in a Windows environment. A demonstration version is available.



 The PLAXIS 2D program including the 2D Dynamics and 2D PlaxFlow modules make up a finite element package intended for the two dimensional analysis of deformation and stability in geotechnical engineering. It is a robust and user-friendly finite element package, developed for Geotechnical Engineering. It offers the tools professionals need in today’s and tomorrow’s world of high-tech building to analyse complex projects.


Geotechnical applications require advanced constitutive models for the simulation of the non linear, time dependent and anisotropic behaviour of soils and/or rock. In addition, since soil is a multi phase material, special procedures are required to deal with hydrostatic and non hydrostatic pore pressures in the soil. Although the modelling of the soil itself is an important issue, many projects involve the modelling of structures and the interaction between the structures and the soil.

Features

New and imroved in PLAXIS 2D 2011:

• Design Approach:
  -A convenient facility to help Plaxis users set up an Ultimate Limit State (ULS) calculation, in a generic way such that any safety approach based on partial factors can be easily introduced. (Eurocode 7, LRFD, etc.)
  -A more structured and efficient way of modelling since you can store a coherent set of partial factors for loads and materials in one location.
  -Design approaches can be easily applied during the definition of phases to make an ULS calculation in addition to a Serviceability Limit State (SLS) calculation
  -Easy exchange of design approaches between different Plaxis projects due to the possibility to  import/export a defined DA.
• Bending Moments: Assign (clockwise and counter-clockwise) bending moments at a specific point on a plate, via the point load tool
• Preview Calculation results: A convenient preview option is available to check model and calculation settings in a graphical 2D or 3D environment. Since calculations can be quite time consuming, it is important to check the model carefully before starting the calculation process.
• Sekiguchi-Ohta model (VIP): A Cam-Clay type effective stress model for the behaviour of clay-type soils. Inviscid model for time-independent behaviour
• Improved Parallelization allowing for even faster multicore computing (VIP)

Modelling:

• Logical geotechnical workflow
• Easy-to-use graphical user interface
• Automatic recognition of soil layers
• Structural elements; plates, geogrids and anchors
• Unlimited combinations of point forces and distributed loads
• CAD import facilities
• Advanced soil models: compression and shear hardening, creep behaviour, cam-clay model, elasto-plastic behaviour for structural elements, Hoek Brown model, Small strain stiffness method
  Soil test

Calculations:

The Staged constructions mode enables a realistic simulation of construction and excavation processes by activating and deactivating soil  clusters and structural objects, application of loads, changing of water tables, etc. The well-proven PLAXIS calculation kernel distinguishes between a Plastic calculation, a groundwater flow and consolidation analysis, and a Phi-c reduction analysis. These can be performed with Updated Mesh to take into account large deformations.

• Convenient and intuitive Phase explorer
• Realistic assessment of stresses and displacements
• Automatic regeneration of construction stages
• Well-proven and robust calculation procedures

Results:

An Extensive range of facilities exists within the PLAXIS Output program to display the results of a finite element analysis.

• Contour, shading, iso-surface and vectors plots
• Extensive report and movie Generator
• Animations
• Curve Manager
• Hint Boxes
• Resulting Force View
