효율적 삼차원 수치모델을 이용한 아스팔트 콘크리트에서의 피로균열성장 해석

초록

This paper presents 3-D numerical simulations of fatigue crack growth in asphalt concrete. The method consists of a linear analysis of an elastic problem at each crack propagation step using the generalized finite element method (GFEM) and use of the elastic-viscoelastic correspondence principle to characterize viscoelastic behavior around a crack front. This strategy enables efficient simulations of viscoelastic fatigue crack growth.
