Abstract A technique for measuring strain with an accuracy of ±100μɛ by direct observation in the scanning electron microscope has been developed and tested. The technique involves placing a fine metallic mesh loosely on the surface of a tensile coupon and observing the motion of the surface with respect to this mesh. It was evaluated by tensile loading of aluminium and carbon fibre-reinforced epoxy specimens for strains up to 600μɛ using an instrumented miniature loading stage. Applications and limitations of the technique have been discussed.
