Special Issue of Experimental Mechanics

We are in the process of organizing a special Issue of Experimental Mechanics, the journal of the Society for Experimental Mechanics. The issue will be devoted to Advances in Residual Stress Technology in honor of Prof. Drew Nelson of Stanford University, for teaching several thousand engineering students about the importance of residual stresses and for developing new optically based approaches for measurement of residual stresses, along with studies of residual stress effects on fatigue. To date, we have accepted proposed paper topics from almost 20 world-leading authors from around the globe.
