NDE 2019 Conference @ Bengaluru
Updated: Jul 4, 2021
This conference was organised by Indian Society for Non-Destructive Testing (ISNT) during 05-07 Dec 2019 at Clarks Exotica Convention & Resort, Bengaluru. It was a well organised event attracted around 1500 people from both academia and industry.
Mr. Mottito Togo (from Honeywell Aerospace) encouraged me to present my DIC research at this conference during a informal conversation with him at Delhi Conference.
Title of the Paper:
Prediction of Failure Process in Geo-Material Using Finite Element based Digital Image Correlation (DIC) Method.
Digital Image Correlation (DIC) is a non-contact and nondestructive testing (NDT) technique, uses digital images and computational algorithms to measure full displacement fields on the surface of the test object. The surface should be randomly speckled to get accurate displacements. A finite element based digital image correlation (FEM-DIC) algorithm is developed by integrating finite element framework in to image correlation process using law of conservation of optical flow. This algorithm is employed for monitoring the deformation process of a concrete cube under laboratory conditions using in-house developed DIC hardware. The full-field displacement plots of experiments, show that DIC can predict the location of crack formations on the surface of the cube well ahead of its visible cracks. DIC can provide new insights into crack propagation as the displacement data is collected continuously during loading and all over the surface. DIC technique have potential applications in structural health monitoring of aerospace, civil, mining structures.
