Normal-Stress and Shear-Stress Gages and Rosettes

  • Charles W. Bert

Abstract

Three-element strain rosettes have long been used in experimental-mechanics investigations on isotropic materials. Also in use for some time have been the concepts of ‘stress gages’ and ‘plane-shear gages’ in which the gage outputs are proportional to the maximum normal stress and maximum in-plane shear stress, respectively. This paper generalizes all of these concepts for applications to fiber-reinforced composite materials. The data-reduction equations presented explicitly incorporate the effect of strain-gage transverse sensitivity.
