The design process for a horizontal creep testing machine is presented along with the material selection of grips for high temperature tensile tests. The design process consisted of creating multiple sketches of the testing machine in order to determine the best design to satisfy the given design parameters. The critical points of the frame were determined and derivations were performed in order to determine the maximum stress at the critical points and the maximum deflection due to the applied load. The information gathered from these derivations will be useful in comparing the two material choices for the frame which are aluminum structural framing and steel.
The material selection process for the grips was also presented. The material of choice for the grips must be able to withstand high temperature as well as have high strength and high stiffness. The economic side of choosing a material was also taken into account in order to determine the material that provides the best performance while minimizing cost. It was determined that the ideal material is silicon carbide and the best shaping process for a small batch size is to use conventional machining.
