Overview Of SAGE CRISP
 SAGE CRISP is a purpose-written Geo-
technical, Finite Element Analysis package
 CRISP (the FE Analysis engine) has been
used successfully by universities and
companies for over 20 years
 Nearly 100 academic papers have been
published using CRISP
Overview Of SAGE CRISP
 SAGE Engineering have added a new user-
friendly Graphical User Interface operating
under Microsoft Windows 95 and Windows
NT.
 The SAGE CRISP software suite comprises:
 Pre-Processor
 FE Analysis Program
 Post-Processor
 Report Generator
 Help on the GUI
 Help on FE errors
Graphical User Interface
 CAD-style, graphical input window allows
meshes to be quickly built and altered
 Graphical selection of nodes, edges and
elements
 Full support for WYSIWYG printing and
clipboard cut-and-paste operations
Graphical User Interface
 Graphically apply displacement fixities to
nodes and edges
 Graphically apply total or excess pore water
pressure fixities to nodes and edges
 Graphically apply point or distributed loads
to nodes and edges
Graphical User Interface
 Graphically add and remove elements to
and from the mesh to simulate construction
or excavation activity
 Graphical representation of each discrete
stage of analysis; including the display of
loads, fixities and construction sequences
 Automatically generate unstructured or
structured finite element meshes
Reporting
 Report on selected input and output data
using the SAGE CRISP Report Generator
 Apply formatting to Reports in a standard
spreadsheet environment
 Store preferred formats as re-usable
Templates that can be applied to any Report
 Print Reports directly, or export the data for
use in other applications
Analysis Types
 Drained, Undrained and Fully Coupled
(Biot) Consolidation analysis
 Two dimensional analysis in Plane Strain or
Axisymmetry
 Three dimensional analysis
(Note: 3D is only available without the
graphic pre and post processors)
Constitutive Models
 Cam-clay based models including
Original Cam clay (half ellipse)
Modified Cam clay (half circle)
Schofield model with no-tension cutoff limits
Three Surface Kinematic Hardening model
Elasto-plastic Models
 Homogeneous, anisotropic, linear elastic
 Non-homogeneous, anisotropic, linear
elastic

failure criteria:
 Mohr-Coulomb
 Drucker-Prager
 Tresca
 Von Mises
Structural elements

Parametric Analysis
 Run parametric studies to examine the
effect of changing:
 Material Properties
 Drainage Conditions
 Construction
Sequences
 Applied Loads
 Numerical
Dependence
 ...and more
 Compare results from parametric analyses
using the SAGE CRISP Post-Processor
Building a Mesh
 Create nodes and elements by drawing them
directly onto the screen
 Use the Automatic Mesh Generator to
quickly and easily build complex finite
element meshes from simple super meshes
 Unstructured and Structured Automatic
Mesh Generators
Unstructured Mesh Generation
 Create a freeform Super Mesh containing
Super Elements of any shape and with any
number of sides
 Finite Elements are generated according to
grading parameters specified at nodes in the
Super Mesh
Structured Mesh Generation
 Create a Super Mesh of quadrilateral Super
Elements
 Finite elements are generated according to
the pattern of divisions specified for each
edge in the Super Mesh
Boundary Conditions
 Fix nodes and edges against horizontal,
vertical or rotational movement
 Apply prescribed displacements
 Drain nodes and edges to either atmospheric pressure, or to a static pressure head
 Set total or excess pore water pressures
 Graphical display of boundary conditions
Pore pressure fixities applied to top surface
Define Material Zones
 Create ‘Zones’ representing homogeneous
regions of soil
 Choose constitutive models and define soil
parameters for material zones via the
Material Properties dialogue box
 Coloured display of material zones
Set-up Insitu Conditions
 Define in situ conditions in terms of:
 Stresses (total or effective)
 Pore water pressures (total or excess)
 Preconsolidation pressure (for critical state
soil models)
 Use the Stress Converter to automatically
calculate the in situ conditions
Set-up Increment Blocks
 An analysis is divided into a number of
discrete stages called Increment Blocks
 Use Increment Blocks to:
 Model each stage of a construction sequence
 Apply new or modified boundary conditions
 Apply new or modified loads
 Allow consolidation to occur
 Control numerical accuracy

Running An Analysis
 The analysis can be run through the Pre-
Processor, or directly by command line
 Progress messages are issued whilst the
analysis is running
 Once complete, all analysis output is stored
in Microsoft Access database file
Post-Processing
 Analysis output can be visualised and
reported on in the SAGE CRISP PostProcessor
 Post processing features include:
 Graphs
 Contour Plots
 Stress State Plots
 Deformed Mesh Plots
 Report Generator
New in version 4
 32bit compatible for Win95 and NT
 Introducing Layers for easy meshing and selection


Overview of the
CRISP Consortium
 The Consortium was setup in 1996 and consists of
various academics and geotechnical experts in the
UK. The Consortium was established by
Cambridge University to take care of development
of CRISP and organise courses.
 In 2000 the Consortium took over the marketing
of SAGE CRISP from SAGE Engineering
 The Consortium’s office is based in South Bank
University, London.

Overview of the
SAGE Engineering
SAGE Engineering Ltd was formed in 1991 having operated since 1984 as
Structural and Geotechnical Engineering Ltd.
From a background of geotechnical site investigation, SAGE had developed
skills in geophysics, geotechnics, rock mechanics, structural and foundation
engineering, pipeline design, and in 1994 Sage Engineering formed a
partnership with Cambridge University to produce SAGE CRISP.
SAGE Engineering’s USA. affiliate, SAGE Engineering Inc, was formed in
1995 by the acquisition of assets and personnel of Geocognetics, Inc., a
Houston-based consulting and engineering services firm with consultants’
finite element experience dating from 1981 in Critical State geotechnics and
from 1967 in structural dynamics.
Overview of the
SAGE Engineering
SAGE Engineering, Ltd released SAGE CRISP with a 2-D Windows-based
graphical user interface in 1996, and in 1997 named SAGE Engineering Inc as
the sole SAGE CRISP distributor in North America.
In 1998 SAGE Engineering, Inc was authorized to make further developments
of the SAGE CRISP program. Current projects include the development of a
3-D interface.
