Description	Journal: Iop Conference Series: Materials Science and Engineering Rocker arm is a reciprocating lever that is used as a tool for internal combustion of the engine to transfer the pushrod movement to the valve stem. Finite Element Method (FEM) uses ANSYS Workbench software to predict stress, deformation and fracture that occurs in the rocker arm hole with two loading models. Rocker arm design using Autodesk Inventor Software and the material used is gray iron cast. The force inputted to the simulation is 550 lbs equal to 2446.52 N. The simulation results show that the equivalent stress, main stress, and maximum shear stress on the loading model 1 are higher than the load model 2. For deformation the value is very low because of the brittle material properties, including the crack simulation test cannot produce J-Integral values and stress intensity factors (K1).
