Abstract

On décrit un procédé et un dispositif pour l'obtention d'une contrainte de compression prédéterminée entre une paire de surfaces de contact. S'agissant par exemple de la face inférieure 16 d'une vis 14 et de la face affrontée 17 d'une pièce 12 à fixer par vissage sur un corps 13, une rondelle 15 comporte une structure poreuse fragile chargée par absorption d'une substance explosive; lorsque la contrainte prédéterminée est atteinte ladite structure se brise et provoque la détonnation de cette substance. L'explosion peut egalement provoquer un blocage de l'assemblage par soudage. Application aux assemblages les plus divers, ainsi qu'au controle de la charge de véhicules ou de moyens de levage.
