|1. (WO2013118434) BLAST TREATMENT METHOD|
|Applicants:||KABUSHIKI KAISHA KOBE SEIKO SHO (KOBE STEEL, LTD.)
|Title:||BLAST TREATMENT METHOD|
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.
