Dr.-Ing. Ashok Kumar Nallathambi obtained his PhD from the Process and Systems Engineering Department, Otto von Guericke University, Magdeburg, Germany in 2010. From 2010 -2018, he has worked in OvGU and interacted with various European metal companies such as AMAG Casting, Swiss Steel, NOVELIS, ALUNORF, BharatForge, etc. His areas of specialization are thermal stresses in heat treatment of metals, material constitutive modeling, and hot & cold cracks.
He is currently working in the Peridynamic methods for predicting the origination of hot cracks during metal quenching process. He established the Metal Quenching Research Laboratory for conducting experiments on semi-solid aluminum plates under cracking conditions.
