... is nonideal. The larger the charge diameter is, the more ideal explosion comes. When calculated borehole pressures were compared to the measured values it was noticed that the constant applied in the formula should vary along the charge diameter. Revised formula demonstrates how the EDZ extend can...

... observations the change of yielding at different scales is investigated. The experiments are conducted on cylindrical samples of sandstone with diameters of 50 and 96 mm. Every specimen was tested at different confining pressures. The distinctions of the initial yield points at different scales are extracted...
