RT Journal Article SR Electronic A1 Papacz, Władysław A1 Walkowiak, Janusz A1 Frankovský, Peter T1 Device for Testing the Fatigue Life of Composite Structural Elements of Vehicles JF Acta Mechanica Slovaca YR 2014 VO 18 IS 1 SP 58 OP 63 DO 10.21496/ams.2014.008 UL https://www.actamechanica.sk/artkey/ams-201401-0008.php AB The paper presents the device of the fatigue tests in the complex load states. The measuring system can measure and record the temperature of the elements tested, the number of fatigue cycles, twisting and bending angles of the sample and its load. The device is used to test the fatigue strength of elements of the carrying structures of the vehicles and machines cophasally loaded with the bending and twisting moments.
