METHOD AND APPARATUS FOR INVESTIGATING MECHANICAL PROPERTIES OF SOFT MATERIALS

摘要

A method and apparatus for investigating subsurface properties of sediment,soil,snow, food stuff and other soft materials incorporates a probe head,preferably in theform of a coil spring that functions as a screw thread, which moves into thesoil, snow,sediment, food stuff or other soft material, isolates a column of the materialand appliestension to that column while measuring the applied force with a force sensor.
