Optical measurement of plastic strain with CCD camera was applied to tension-torsion combined loading tests of aluminium tube specimens. The axial elongation and the shear strain were successfully measured with the accuracy of 0.5% strain up to 30% strain range, although the change of diameter was detected by another direct method.
