J-적분을 통한 아스팔트 포장체의 피로 균열 성장 분석
유성문(Yu, Seongmun),차우딘단(Chau Dinh Thanh),지광습(Zi, Goangseup) 한국구조물진단유지관리학회 2009 한국구조물진단학회 학술발표회논문집 Vol.2009 No.2
This paper studies fatigue crack growth of asphalt using J-integral method. Asphalt pavements can be cracked under repeated vehicle loadings, which is called fatigue crack. So precise prediction on the fatigue crack growth in the asphalt pavement is necessary for efficient maintenance works. To analyze fatigue crack growth, energy based J-integral method is used in this paper. Using that method, the analysis simulates the fatigue test results appropriately.
