Digitized edition from print [produced by Defence Research and Development Canada]. Includes bibliographical references (page 60). To examine the feasibility of using the pressure-sinkage data obtained using a Rammsonde as input to the computer simulation model NTVPM-85, developed by Vehicle Systems Development Corporation (VSDC), for predicting tracked vehicle performance over snow, a series of measurements of the pressure-sinkage relationships of fresh and preconditioned snow was made using a Rammsonde and a bevameter. In addition, the shear strength of the snow was also measured using a bevameter shear device and a hand-held shear device. This report describes the Terrain Data Analysis Software (TDAS) developed by VSDC for processing experimental data obtained using the Rammsonde, the bevameter and the hand-held shear device. The instructions for the operation of the TDAS and for the preparation of input data files are given. Sample output from the TDAS is also presented. Shear (Mechanics) Data processing.
