Virtual Conference
7-9 August 2021
Conference Chairs: Professor Hari Arora (Swansea University) and Dr Daniel Mulvihill (University of Glasgow)
The conference was held at the University of Sheffield in the centenary year for the Departments of Mechanical, Civil and Electrical and Electronic Engineering. Steeped in industrial and Victorian heritage, the conference showcased novel and innovative research in Experimental Mechanics, fitting well in the latter two activities.
In additional to a stimulating technical programme and the ‘traditional extras’, including the BSSM EMex exhibition of experimental mechanics and the BSSM Young Stress Analyst Competition, delegates also had the opportunity to explore Sheffield’s industrial past at the conference dinner at the Kelham Island Industrial Museum.
