Evaluation of mechanical characteristics of shape memory alloys under cyclic loading in torsion
German, Roman ; Štěpánek, Roman (referee) ; Horníková, Jana (advisor)
The main aim of this thesis is to process the results of fatigue tests of wires of a NiTi shape memory alloy subjected to symmetric cyclic torsion. The first part of this work is dedicated to literature research about NiTi alloys, their response to cyclic loading and the specific features of torsion loading. The second part contains a review of the influence of heat treatment and strain amplitude on the ability to dissipate mechanical energy, changes in mechanical properties and fatigue life of the tested material.
