Abstract : The dynamic behavior of structure with the presence of inclined edge crack is an emerging topic in the era of structural dynamics. In the present analogy, a novel method is focused to investigate the dynamic response of an inclined edge cracked simply supported structure subjected to moving mass. The responses of the beam structure subjected to traversing load are calculated with different crack inclination angles and crack depth using Duhamel integral approach. For the authentication of the numerical approach, the finite element analyzes (FEA) is accomplished to corroborate the exactness of computational approach (Duhamel integral approach). The FEA approach has been conducted using the commercial ANSYS WORKBENCH software. The significance of the crack parameters (crack inclination angle and crack depth) and moving mass parameters (moving speed and magnitude of moving mass) on the responses of the beam are investigated. The numerical analyzes followed by FEA approaches are illustrated for different crack angles, crack depth, moving speed and moving mass. The results which are obtained from both the numerical method as well as FEA approach are compared with each other. As per the results are concerned, the applied numerical analogy converges well towards the FEA approach. So the Duhamel integral method is found to be convergent and can be useful to obtain the response of structure under transit mass.
