This paper presents a new approach to the evaluation of dynamic soil strength based on the hypothesis of discreteness of the deformation process - a method of self-excited vibration. This method was first discovered at the sandy soil shear test. The destruction of the soil is viewed as cyclical and consists of two phases: the static and dynamic. On static stage deformation is slow, with energy accumulation. In the dynamic there is a rapid discharge, accompanied by a sharp increase in strain. Self-excited vibration...

Aim of this paper is to provide the overview of ecological friendly mechanical engineering through design solution in the field of material handling. There can be achieved a significant reducing of energy consumption with advantage of maintenance simplicity by decreasing level of the automation and the design complexity. Model situation is dealing with change of the material position orientation by using minimum of external forces and processes. The orientation change is induced by motion of the material along pre...
