EMRTC typically uses this type of modeling when designing objects that must survive shock environments such as explosions and gun firings. EMRTC also has several first-principle hydrodynamic codes, including CTH from Sandia National Laboratories

• . Mine Detection Evaluation The Countermine Test Site was developed to test and evaluate technologies for the detection and destruction of anti-tank and anti personnel mines. The site consists of support facilities and 100 and 200 meter oval flat tracks. Inert or live mines can be located on the tracks. Remotely operated robotic detection/destruction devices can b
