The document describes the design and fabrication of a fatigue testing machine for sheet metal. It discusses fatigue failure and standard fatigue testing methods. It then details the design of a new low-cycle fatigue testing machine, including components like the load-producing mechanism. Specifications for pulleys and load calculations are provided. The machine is tested by applying different cycle counts to steel sheet metal specimens and analyzing fatigue strength. The conclusions are that the designed machine performs satisfactorily in testing sheet metal fatigue up to 100,000 cycles and has potential for composite and fiber materials testing with low cost.
