Abstract : In order to determine the strains and the stresses which arise in one of the sides of leaf specimens, there was applied, by the photocontact method, a net consisting of intersecting circles of diameter 10 mm. The scale of the net was applied on a leaf of transparent plastic and was measured with a travelling microscope with precision of 1 micron. During the course of the experiment, the circles were transformed into ellipses, the size of the axes of which allowed the strain to be determined. Since alloys VT1-2 and OT4-1 exhibit transversal isotropy, an attempt was made to obtain the equations of the connection between the strains and stresses on the basis of the generalized Hooke law. The equations obtained were subjected to experimental confirmation by means of the extension of specimens in which the working length was equal to the breadth. (Author)
