Analysis of Progressive Fracture in Concrete using Finite Elements with Embedded Discontinuous Line

내부 불연속 요소를 사용한 콘크리트의 파괴진행해석

In this paper, finite element with embedded discontinuous line is introduced in order to avoid the difficulties of adding new nodal points along with crack growth in discrete crack model. With the discontinuous element using discontinuous shape function, stiffness matrix of finite element is derived and dual mapping technique for numerical integration is employed. Using the finite element program made with employed algorithms, algorithm is verified and fracture analysis of simple concrete beam is performed.
