Full Length Symmetric Versus Partial Length Un-symmetric Pin Loading Failure and Analysis for Clevis Attachments

In this paper, testing failure of the clevis–pin attachments for full length symmetric versus partial length un-symmetric configuration is considered. Theoretically and analytically it can be shown that due to higher stress levels in the partial length un-symmetric pin clevis configuration failure occurs sooner than in a full length symmetric pin clevis configuration. However, here by placement of the two different configurations at opposite ends of one axial tensile test setup the theory was put in test. The test results also indicated that the partial length clevis–pin attachment fails sooner than the full length clevis–pin attachment. Experimental procedures are described here in this paper. Both theoretical and finite element analyses are performed to validate the failure.
