Click the small icon below to download the CRASHEX program.
Immediately upon download the CRASHEX program can be installed and used in a "Demo" mode which provides a family of Demo files with representative configurations. These are soluble on command by principles of momentum and energy --- either by reversion to the original premises of NHTSA's CRASH3 program, or by its refinements and extensions as published by Fonda. The program graphs the results both in plan view of the scene and as diagrams of damage and vector summation, and issues an array of numerical Results. All of the foregoing are then summarized in a one-page Report with full input and output numerics and reduced-scale graphics. Full-size graphics can be captured and printed using any screen capture program.
Upon entry of a purchased key
(see Purchase) the Demo becomes a fully enabled program ready for the entry of the input data of any of your your subject case. This can be done from your investigation, whether item by item or by revision of any demo case. At any time any case can be modified either numerically or by drag-and-drop in the graphical site display. At any time the Report described above may be printed. Any selected base case may be instantly rerun upon entry of any deviation, for identification of influence coefficients or performance of Reliability Reconstruction by means of Finite Difference Analysis.
