Abstract:

In construction and fabrication industries, the TMT bars are required to test for permanent deformation within elastic limit. TheSpectro Lab needs the extensometer to test such jobs with 300mm gauge length. The cost and availability of 300mm gauge length extensometer is major concern for Spectro Lab. Hence, the Manav Rachna Innovation and Incubation Centre (MRIIC) provided the solution and modification on the problem faced by Spectro Lab. The fixture for holding the TMT bars and increments/extension to existing extensometer have been successfully developed and fabricated at MRIIC. The developed fixture and extension accessories found to be suitable and highly useful to the Spectro Lab by precise experimentation and commercial aspects in very reasonable cost.
