Abstract
In the present paper, investigation of a crack in a curved cantilever beam is studied. The crack in the beam is modeled using a rotational spring with stiffness defined in terms of depth of the crack. The equation of motion for the cracked cantilever beam is solved using Differential Quadrature Element Method (DQEM). The Finite Element Analysis (FEA) using ANSYS is also carried out for the cracked curved beam. The severity of the crack with its location on cross-section of the beam is studied using DQEM and FEA. Many numerical examples are demonstrated to verify the aforementioned effects. It is concluded that both the approaches are very close to each other for different crack locations and severities.
