Observation of fracture surfaces using SEM: crab claw

We conducted an observation of the fracture surface of the crab claw that was damaged due to long-term use!

We conducted observations using SEM on the fracture surface of a crab claw that was damaged due to long-term use. At the edge of the fracture surface, traces of plastic deformation (dimples) were observed, suggesting that it broke due to being pulled. In the central area of the fracture surface, the appearance was different, with only slight dimples visible, and there was almost no indication of having been pulled apart. It could be inferred that there were already voids present in the central area. Various other observations are also possible, so please feel free to contact us. [Overview of Fracture Surface Observation] ■ Edge of the Fracture Surface - Traces of plastic deformation (dimples) were observed. ■ Central Area of the Fracture Surface - There was almost no indication of having been pulled apart. - It could be inferred that there were already voids present. *For more details, please refer to the PDF document or feel free to contact us.
