Fracture of a weightless half plane or half space by a rigid punch with an exponential condition of limiting equilibrium
- 14 Downloads
For a medium with an exponential condition of limiting equilibrium, solutions are obtained to the problems of the fracture of a half plane or half space (axisymmetric problem) by a rigid punch (ideally smooth or rough). These solutions can also be used to estimate the supporting capacity of soils or roofs of workings when broken by a pillar, rectangular in plan, with real roughness.
Replacement of the exponential condition of limiting equilibrium by the condition of Tresk or Mises in the limiting equilibrium calculations can lead to distortions in the results of the calculations.
