METHOD OF SHEARING TEST OF A PARALLELOGRAM-SHAPED FLAT SAMPLE UNDER TWO-DIMENSIONAL LOAD

摘要

The proposed method of shearing test of a parallelogram-shaped flat sample under two-dimensional load consists in applying two pairs of identical and oppositely directed forces to the sample. The sample of thickness h has the sides a1 and a2, with an acute angle between the sides. The sample is installed with the possibility to freely rotate under the applied forces in the longitudinal plane. The force of a1h is applied to each side a1, and the force of a2his applied to each side a2. The angle between the forces applied to the adjacent sides of the sample, is determined as: = . In the equation above, y1 and y2 are specified normal stresses, is a specified tangential stress.
