Stress Analysis of a Lug Loaded by a Pin,

A method is described which gives a refined stress analysis of a flexible lug loaded by a rigid pin. Using the finite element approach the flexibility of the lug is assessed the contact pressure distribution is then determined by an iterative procedure which allows for compatibility of displacement between pin and lug. Having found the contact pressure the stress distribution throughout the lug is determined by a routine finite element analysis. This method is applicable to cases of neat, clearance or interference fit pins. Numerical results for neat fit pins show reasonable agreement with some test data. Author
