Description

To simulate damage, cracks with a fixed width of 1 mm and a length of 25 mm were introduced, with varying depths of 2 mm, 4 mm, and 6 mm. Crack locations were varied from 0 to 700 mm in 25 mm increments from the fixed end, resulting in 87 damaged states. Including the undamaged state, a total of 88 cases were analyzed using numerical modal analysis in ANSYS. These variations in crack depth and location led to random changes in the beam’s natural frequencies. The bending Modes of Frequencies using ANSYS of Damaged states are tabulated below Table 4.
