British materials scientist
Angus J. Wilkinson is a professor of
materials science based at the
Department of Materials, University of Oxford . He is a specialist in
micromechanics ,
electron microscopy and
crystal plasticity .
[1]
[2] He assists in overseeing the MicroMechanics group while focusing on the fundamentals of
material deformation . He developed the
HR-EBSD
[3]
[4] method for mapping stress and
dislocation density
[5] at high spatial resolution used at the micron scale in mechanical testing
[6]
[7] and micro-cantilevers
[8] to extract data on mechanical properties that are relevant to materials engineering.
