Abstract
PURPOSE: To photograph isoclinic lines alone in clear black stripes in stress analysis on a structure, by applying initially a stationary load to a test piece, and changing later the stationary load to an oscillatory load.
CONSTITUTION: A predetermined value is set in a stationary load pressure switch 22, and a predetermined load is applied to a test piece 5. A hydraulic pressure is then applied to a ram 16 and bellows 19 by a pump 18. An oscillatory load pressure switch 23 is then turned on to rotate a cam 26 and apply oscillations to the bellows 19. As a result, the hydraulic pressure in the bellows 19 fluctuates so that an oscillatory load is applied to the ram 16. When a load is applied to the test piece 5 in the same direction, the stripes representative of isoclinic lines are not moved. The stripes representative of isoclinic lines are varied or moved with variations in the magnitude of the load applied to the test piece so that isoclinic lines only can be photographed before the load is varied.
