Plastic Deformation in Circular Shafts

Plastic Deformation in Circular Shafts

When materials are subjected to forces that surpass their yield strength, they undergo a process known as plastic deformation. This results in a permanent alteration or strain in their structure. This concept can be specifically applied to circular shafts, where the deformation leads to a change in its shape. The precise evaluation of this plastic deformation requires understanding the stress distribution within the circular shaft, which is achieved by calculating the maximum shearing stress in...

Experimental setup to measure coupling power changes with fiber bending radius.
Testing the sensor's response to displacement at different temperatures and speeds.

Main Results:

The sensor demonstrated satisfactory performance up to 140 mm displacement at room temperature and 70 °C.
Linear output observed between 110 mm-140 mm displacement under specific conditions.
Achieved a sensitivity of 19.805 nW/mm and a resolution of 0.12 mm.

Conclusions:

The proposed POF-based displacement sensor offers a simple, reliable, and wide-range measurement capability.
Its robustness to temperature and speed variations indicates suitability for diverse applications.
