Evaluation of O-ring stresses subjected to vertical and one side lateral pressure by theoretical approximation comparing with photoelastic experimental results

Contact and internal stresses of an elastomeric O-ring which is subjected to a vertical compression and lateral pressure at one side are evaluated experimentally and theoretically for a failure analysis and a life prediction. In the experiment, the O-ring specimen was made of epoxy resin. The applied fractional compression was 20% and the lateral pressure was varied as 1.96, 2.94 and 3.92 MPa. The photoelastic experimental hybrid method was used...
