Focuses on state-of-the-art testing techniques forcharacterizing the multiaxial fatigue and deformation behaviors ofmonolithic and composite materials. 14 peer-reviewed papers dealwith both experimental and theoretical aspects of the multiaxialfatigue and deformation behaviors of structural materials. In 4sections: Multiaxial Testing Facilities; Multiaxial Deformation; Multiaxial Fatigue; and Structural Failure and CrackPropagation Under Multiaxial Loading.
