Identification of crack location in metallic biomaterial cantilever beam subjected to moving load base on central difference approximation

Abstract If not detected early, the cracks in structural components may ultimately result failure of structure. This issue becomes even more critical when component under investigation is a prosthesis placed human body. study presents crack location identification method based on time domain cantilever beam metallic biomaterials (CBMB). The absolute difference between central approximation root mean square (RMS) displacement points cracked and uncracked beams was applied as indicator. Captured time-domain data (displacement) at each node were processed into RMS displacement. Then, could be by sudden change feasibility effectiveness proposed validated numerical simulations. finite-element simulation CBMB with transverse notch analyzed study. or along moving load various locations. A set experiments calculations performed to determine whether would accurately detect compared found an exact solution method. results showed that only able analytical but also robust against noise: it precisely 5% noise.
