Document Type and Number:
WIPO Patent Application WO/2013/118434
Kind Code:
A1
Abstract:
Provided is a blast treatment method with which the object to be treated can be treated more reliably and efficiently. This method includes: a step wherein an explosive is detonated inside a pressure container (30) comprising an elasto-plastic metal, thereby imparting to the pressure container (30) an initial load wherein the first-order + second-order stress generated in at least a portion of the structural components of the pressure container becomes a stress that is included in a plastic region exceeding the elastic region, thereby generating a shakedown in the pressure container (30); and a subsequent step wherein a treatment-use explosive (50) is detonated within the pressure container (30), thereby blasting the object (10) to be treated.
