An inexpensive servo‐controlled electrohydraulic fatigue machine, capable of a maximum load of 22.2 kN (5000 lbf) and a maximum servo‐controlled strain rate of 0.2 sec−1, is described. Its primary capability is to perform load and strain‐range controlled fatigue tests conducted at constant strain rate feedback. In addition, the machine is capable of performing constant strain rate tensile tests and closed loop stress relaxation tests. The results of some initial fatigue tests are presented.
