In a wide range of practical applications, plastic bending analysis methods are important in understanding the structural capability of a part beyond the elastic range of a material. In the senior design project of which I am a member, a 3/8 inch diameter pin is a key structural component for a mooring cam product targeted at marine applications. The goal of this project is to compare two analysis methods of plastic bending in this pin to elastic calculations and experimental data. The two plastic analysis methods used are the Cozzone method and material non-linear finite element analysis with three-point bending boundary conditions. The Cozzone method employs an analytical technique to solve for the plastic moment, while the non-linear finite element model is solved in ANSYS software. The deflection from the non-linear finite element model is further compared to the experimental data of a three-point bending test. The results of the finite element model and the Cozzone method show that the 1040 steel pin would fail under a max load of 3300 lb. Additionally, the finite element model did not match the experimental results.
