NIT-R Secures Patent for Machine to Measure & Predict Lifespan of Materials

In India, the National Institute of Technology Rourkela (NIT-R) is one of the premier national-level institutions for technical education. Formerly known as the Regional Engineering College Rourkela, NIT-R is funded by the Government of India. It has recently secured a patent for developing a machine to measure and predict the lifespan of composite materials used in the manufacturing and construction sectors.

The 2018 BTech (Bachelor of Technology) batch students, namely Souvik Biswas and Chetan Kumar Hirwani, along with their professor of Mechanical Engineering, Subrata Kumar Panda, developed the machine titled ‘Fatigue and Creep Testing Machine for Nonmetallic/Composite Materials.’

According to NIT-R sources, the trio, on behalf of NIT-R, had filed the Patent Application for the innovation in question in 2018. Under the Indian Patents Act of 1970, the Patent Office of the Union Government has recently granted it approval for twenty years. They stated that the Fatigue and Creep Testing Machine for Nonmetallic/Composite Materials provides an efficient way of estimating the fatigue life-cycle of composite panels.

Composite panels refer to sandwich structures comprising several layers bonded together to create cored laminates, multilayer sheets, or industrial structural panels. They are manufactured from a wide variety of plastic, metal, ceramic, glass, wood, and fiber-based composite materials.  They are largely used for roof construction on commercial buildings, internal structures, and external walls.

Professor Panda, while elaborating on the functionality of the machine in question, said that when a person uses the charger of his mobile, its wire often gets damaged due to extensive folding, messing it up, or using it. He mentioned that through this machine, a person would be able to estimate how many times the bending or folding of a flexible material could be done before it fails. In the same way, according to him, when composite panels are used in constructing buildings or any other scenario where bending or folding is a common mode of failure, a person can predict the entire product life cycle. Professor Panda also stated that the machine is expected to have extensive utilization in aviation, automobile, defense, and allied industries. For more visit:
