Structural geology software on the web:
Stereonet with Google Earth link, Fault slip analysis (FaultKin), trishear (FaultFoldForward), StrainSim etc. for Mac and Windows by Rick Allmendinger.
Stereonet3D (Stereonet with 3D view and export to Google Earth), GeoCalc (Vectors and tensors calculator), SSPX (strain modelling from displacement/velocity data), Trishear3D (3D forward fault related folding), Backstrip (1D backstripping of sedimentary strata), and Flex2D (flexural analysis for constant or variable elastic thickness plates).
Strain program written by Chris Warren and Paul Karabinos at Williams College. Java, all platforms.
Stereo plotting program (web-based) with a nice 3D option. Also check out the other excellent 3D programs of Visible Geology.
Great plotting program that does stereonet projections, rose diagrams, Flinn plots, ternary plots and more. By Carlos Grohmann and G. Campanha.
Frederic Vollmer'splotting software: Stereographic projections, circular histograms, spherical statistics, and fault slip and spacial analysis.
A nice selection of strain programs that closely relate to Chapter 2 (Deformation).
Very useful strain program by Frederic Vollmer.
Great programs for strain analysis and plotting in Flinn diagram, Hsu diagram and more. Requires Mathematica™. By Matty Mookerjee.
Two useful program written by Jiri Rez for Windows.
