Size effects in yield and plasticity under uniaxial and non-uniform loading: experiment and theory
This paper develops a theoretical explanation for size effects in small volumes of material based on the mean free path of dislocations. Experiments on long thin copper wires in torsion and tension allow the distinction between different theoretical approaches to be made, leading to a more robust theory of the origin of mechanical size effects. The paper is a product of a long term research programme in small scale plasticity funded under EPSRC Grant No. EP/C518004/1. This and related work led to an invited talk at the 2012 Gordon Research Conference on ‘Thin Film and Small Scale Mechanical Behavior’.
