Abstract:
(EN) The present invention relates to a method for inhibiting crack growth in a wall portion. A method for inhabiting crack growth in a wall portion according to an embodiment of the present invention comprises: an injection step for injecting working fluid in a crack; a vibration step for vibrating the working fluid in a direction from an opening of the crack to an inner side of the crack; and a deformation step for generating residual compressive stress at an inner end of the crack by generating pores in the working fluid inside the crack.
(FR) La présente invention concerne un procédé d'inhibition de la croissance de fissures dans une partie de paroi. Selon un mode de réalisation de la présente invention, un procédé d'inhibition de la croissance de fissures dans une partie de paroi comprend : une étape d'injection consistant à injecter un fluide de travail dans une fissure ; une étape de vibration consistant à faire vibrer le fluide de travail dans une direction allant d'une ouverture de la fissure vers un côté interne de la fissure ; et une étape de déformation consistant à générer une contrainte de compression résiduelle au niveau d'une extrémité interne de la fissure par génération de pores dans le fluide de travail à l'intérieur de la fissure.
(KO) 본 발명은 벽부의 균열 성장을 억제하는 방법에 관한 것이다. 본 발명의 일 실시예에 따르면, 벽부의 균열 성장을 억제하는 방법은 균열에 작업유체를 주입하는 주입단계; 상기 균열의 입구에서 상기 균열의 내측을 향하는 방향으로 상기 작업유체를 가진시키는 가진단계; 및 상기 균열 내의 상기 작업유체에 기공을 발생시킴으로써 상기 균열의 내측 단부에 압축 잔류 응력을 발생시키기 위한 변형단계를 포함한다.
