Checking without damaging: IIT-Madras works on advanced tech for disruptive material testing

From sensors detecting leaks in pipelines, tanks, bridges and dams without tearing those down to robots for ending manual scavenging — IIT-Madras has established itself as a global centre of excellence for developing disruptive material testing technology. “Non Destructive Evaluation” (NDE) is the broad name given to the field of testing and analysis used by industry to characterise components or structures for indicators of performance degradation, without causing damage to the original part.
