Abstract
Stresses occurring in a stepped rounded D-ring designed to have a ratio of H-1/H-2 = 3.0 and compressed to 20% squeeze and pressurized with internal pressures of 0 MPa, 0.98 MPa, 1.96 MPa, 3.92 MPa, 4.9 MPa and 5.89 MPa are analyzed using photoelastic experimental hybrid method. It was observed that when a pressure of 0 MPa and 20% compression are applied, the photoelastic isochromatic fringes of the stepped rounded D-ring with a ratio of H-1/H-2 = 3.0 were almost symmetrical. However, as the applied internal pressure increased, the circular portion of the D-ring moved over the step on the front side along the points 1(r)-2(r) towards the restraining wall of the front side of the groove. During the motion of the circular portion, the space between the restraining wall and the step on the front side was slowly filled; but unlike the D-ring with a ratio of H-1/H-2 = 1.0 where complete filling occurred earlier before extrusion, complete filling of this space delayed until the portion of the D-ring near the extrusion gap extruded. It was further noted that an internal pressure of up to 5.89 MPa was required to initiate extrusion in the D-ring with a ratio of H-1/H-2 = 3.0.
