soilmechanics theory and hands-on experience in laboratory testing of soils. The Soil-MIST (ModelInstruction and Simulated Testing) program was developed to combine the two, by teachingtheoretical concepts of constitutive modeling in the more familiar context of laboratory strengthtests. It is an outgrowth of a proposed “virtual reality” soil testing environment1. As such, abeta version of the software was first developed in Summer 1997 as simply a test simulator,where the user supplied data to define the soil to be tested, to specify the loading and drainageconditions, and to control how results were displayed. The Modified Cam Clay (MCC)constitutive model was used to predict results.The initial version of Soil-MIST had three data input screens
