My name is Shanmukha Rao Moturu (Shan Moturu), I am from Andhra Pradesh, India. I joined the Materials Engineering Group at the Open University as a full time research student in October-2010. Prior to the Open University I was working as a lecturer at Avanthi Postgraduate College affiliated to Osmania University Hyderabad from Dec 2005-June 2007.

From Aug 2005 to Dec 2004 I worked as research project student at Radio Chemistry Lab of Indira Gandhi Center for Atomic Research, Kalpakkam, Tamil Nadu, India on Phase diagrams of molten salts.

My Research

The aim of this PhD project is to investigate the issues that affect the reliability and accuracy of residual stress measurements made in welded components using the neutron diffraction technique.

I am using Monte-Carlo computer simulation codes to investigate, in detail, the characteristics of specific neutron diffraction instruments and sample materials in order to identify aspects of instrument design or experimental practice that could be improved.  

In parallel, I am conducting experiments on Austenitic stainless steel weld metals using neutron diffraction measurements at ISIS (Oxford) and SNS (USA). In addition to neutron diffraction, I am using the complementary techniques of X-ray diffraction and electron microscope work, etc for the purpose of helping to understand the characteristics of the weld material as they might affect measurement by neutron diffraction.
