Extensometers have been used for decades to find defects in material and were always fascinating to Nikhil Gupta, associate professor in the department of mechanical and aerospace engineering at New York University, mainly for their use in the field of aircraft safety. Now he has conceived and designed his own fiber-optic extensometer.
“When you look at it in terms of new aircraft made of composite material and already reinforced with fibers, a thought that comes to mind is, ‘If you can replace existing instruments with instruments that utilize optical fiber and can look at the stress data, it can be a big help,’” he says.
