Abstract The paper describes a reusable biaxial-strain transducer consisting of a delta-shaped element in the form of a hollow equilateral traingle, with legs mounted perpendicular to its plane at the apices. The legs terminate in hard styli which are impressed into a test surface by axial forces acting on the legs. When the surface is strained, the displacements of the styli induce bending and torsional strains in the arms of the delta element. Strain gages mounted longitudinally on the arms detect the bending strains. It is shown that the strain in any arm is proportional to the strain in the test surface in the direction parallel to the arm. An instrument with a gage length of one inch is described and experimental results show that it has an accuracy of better than one percent.
