Structural condition assessment based strain-stress behaviour for railway welded rail joint using rosette fibre Bragg grating optical sensor

open access: yesResults in Engineering, 2023
The rail provides a medium for trains to operate along and a support system for the cargo trains to carry. Proper caution should be exercised when handling the thermite welded rail, as it can be vulnerable to damage and failure if not properly maintained.
