Ultrasonic fatigue tests were carried out on the plastic m.terial Nylon 6. Special attention was devoted to the tem.erature control in order to avoid physic-chem.cal transform.tion of this low m.lting point m.terial. Under ultrasonic fatigue tests, im.ortant heat dissipation takes place at the narrow section of hourglass shape specim.n leading to high tem.erature at this zone. The specim.n was calculated to m.et the resonance condition with the sm.llest dim.nsions at its narrow section, with aim.to reduce the tem.erature gradient at this zone of this non heat conducting m.terial. Tem.erature at narrow section was m.intained lower than 45℃ using a cooling system.with cooling air;under this condi- tion the ultrasonic fatigue tests were perform.d. Experim.ntal tests were carried out at low loading range (9 - 12.5% of the elastic lim.t of m.terial) in order to control the highest tem.erature and to avoid that specim.n was out of resonance condition. Experim.ntal results are analyzed together with the fracture surfaces and conclusions are presented concerning the ultrasonic fatigue endurance of this polym.ric m.terial.
