Dr Muhammad Shamir obtained his Undergraduate and Masters degree in Materials Engineering from GIK Institute of Engineering Sciences and Technology, Pakistan, in 2012 and 2015 respectively. In 2017 he joined Coventry University, UK for his PhD study on fatigue crack initiation and small crack propagation of additively manufactured Ti-6Al-4V which was jointly funded by BAE System and Coventry University. During his PhD, he investigated the effect of defects on crack initiation and early-stage propagation in a wire + arc additive manufactured (WAAM) Ti-6Al-4V. His research demonstrated that the fracture mechanics approach can be used for predicting the fatigue life of WAAM titanium alloys in as-built conditions and, hence, can be a tool for decision making on the level of surface machining of additive manufactured parts. In March 2021 he joined School of Water Energy and Environment, Cranfield University as Postdoctoral Researcher on an EPSRC funded project to study the Structural Integrity of Additive Manufactured Offshore Structures. The project was focused on life enhancement of offshore wind turbine structures using WAAM technology. The project was extended and moved to Naval Architecture, Ocean and Marine Engineering, University of Strathclyde and was completed successfully by November 2022. Dr Shamir later joined Advanced Manufacturing Research Centre (AMRC), University of Sheffield as a Technical Lead-additive manufacturing in November 2022 and has been working on different WAAM technologies.
Dr Shamir has published in several peer reviewed journals related to additive manufacturing, welding and aerospace technologies.
