Im having difficulties performing stress analysis on a component i designed for a project. I've ran FEA in solidworks giving me the Von Mises stress and the displacement due to the load. My supervisor has asked me to back up the fea with hand calculations but im have a hard time. The part is a double fixed end beam with two moments acting in the middle symmetrically. Attached you will find a schematic of the part. The material used is 6061-T6. Any help or advice would be greatly appreciated.
