Rocscience Phase2 8.005: The Ultimate 2D Elasto-Plastic Finite Element Program for Geotechnical Engineering

Geotechnical engineering is a branch of civil engineering that deals with the analysis, design and construction of structures and systems that interact with the ground, such as foundations, tunnels, slopes, dams, retaining walls, etc. Geotechnical engineering requires a thorough understanding of the mechanical behavior of soils and rocks under various loading and environmental conditions, as well as the ability to model and predict their response using numerical methods.

One of the most advanced and versatile numerical methods for geotechnical engineering is the elasto-plastic finite element analysis, which can simulate the behavior of materials that undergo plastic deformation under stress. Plastic deformation is a permanent change in shape or size of a material due to applied forces, such as shear, compression or tension. Plastic deformation occurs when the stress exceeds the yield strength of the material, which is the maximum stress that can be sustained without permanent deformation. Plastic deformation is often accompanied by strain hardening or softening, which is a change in the material's resistance to further deformation.

Elasto-plastic finite element analysis can account for complex material models that capture the nonlinear and anisotropic properties of soils and rocks, such as Mohr-Coulomb, Hoek-Brown, Cam-Clay, Drucker-Prager, etc. Elasto-plastic finite element analysis can also incorporate various failure criteria and post-failure behavior of materials, such as tension cut-off, shear banding, dilation, etc. Elasto-plastic finite element analysis can handle large deformations and displacements, as well as contact and friction between different materials or interfaces.

Rocscience Phase2 8.005 is a software program that uses elasto-plastic finite element analysis to model geotechnical problems involving underground or surface excavations in rock or soil. Rocscience Phase2 8.005 is a powerful 2D elasto-plastic finite element stress analysis program that can be used for a wide range of engineering projects involving underground or surface excavations in rock or soil. Rocscience Phase2 8.005 can be used to solve problems involving:

Plane strain or axisymmetry

Elastic or plastic materials

Staged excavations (up to 50 stages)

Multiple materials

Support (bolts / shotcrete)

Constant or gravity field stress

Jointed rock

Groundwater (include pore pressure in analysis)

Rocscience Phase2 8.005 consists of three program modules: MODEL, COMPUTE and INTERPRET. MODEL is the pre-processing module used for entering and editing the model boundaries, support, in-situ stresses, boundary conditions, material properties, and creating the finite element mesh. COMPUTE is the solver module that performs the elasto-plastic finite element analysis and generates output files containing the results. INTERPRET is the post-processing module that allows the user to view and analyze the results in various formats, such as contours, vectors, graphs, tables, etc.

Rocscience Phase2 8.005 has many features that make it user-friendly and efficient for geotechnical engineering applications, such as:

A graphical user interface (GUI) that allows easy input and editing of data using menus, toolbars, dialogs and mouse operations.

A built-in CAD system that enables drawing and editing of complex geometries using lines, arcs, circles, polygons, etc.

An automatic mesh generator that creates high-quality triangular or quadrilateral elements with user-defined size and refinement options.

A library of predefined material models that can be easily selected and modified by the user.

A variety of support options that can be applied to any part of the model boundary or interior nodes.

A flexible staging feature that allows sequential excavation or loading of any part of the model in any order.

A powerful solver that uses an efficient iterative algorithm to solve large nonlinear systems of equations with sparse matrices.

A comprehensive output system that provides detailed information on stresses, strains, displacements, forces, factors of safety, etc.

A versatile visualization system that allows the user to display and manipulate the results in different ways, such as color maps, contour plots, vector plots, profile plots, histograms, etc.

A report generator that creates professional-quality reports with tables, graphs and images.

Rocscience Phase2 8.005 is a state-of-the-art software program that can help geotechnical engineers to design and optimize their projects involving underground or surface excavations in rock or soil. Rocscience Phase2 8.005 can handle complex and realistic scenarios with accuracy and efficiency, and provide valuable insights into the behavior and performance of geotechnical structures and systems.
