Background & Academic History:

I am Nida Naveed. My home country is Pakistan, I did my bachelors in Civil Engineering from NED University Engineering & Technology, Karachi Pakistan in 2004, and then I did my masters in Structural Engineering from the same university in 2007. During my masters I got the opportunity to teach at undergraduate level at NED University as an Assistant Professor. I joined the Open University as a full time research student in 2011, I found the Open University a great place of study, here supervisors, colleagues and all supporting staff are very corporative, and the labs are fully equipped with the state of the art technology. I am so glad to be associated with the Open University.


Research Area:

Residual stress is one of the main factors affecting the durability of the manufactured components subjected to external loads. Residual stresses are caused by incompatible internal permanent strains or non-uniform plastic flow. The evaluation of these stresses is essential for accurate structural integrity assessment. The contour method is one of the most recent methods to evaluate residual stresses. The contour method was invented in 2001 by Mike Prime of Los Alamos laboratory. It is a destructive technique.

The aim of my research is to develop the contour method and to extend its range of applications beyond its current scope, to higher sensitivity and resolution, more complex geometries, and a wider range of length scales. The contour method can be used to measure the full cross sectional profile of the component of residual stress normal to the cut surface, but there is the potential for work in this area for measuring the full three dimensional stress tensor in complex engineering components, especially when it is combined with other methods.
