خستگی و تغییر شکل چندمحوری: آزمایش و پیش‌بینی (انتشارات فنی ویژه ASTM)

This comprehensive new ASTM publication examines state-of-the-art multiaxial testing techniques and methods for characterizing the fatigue and deformation behaviors of engineering materials. 25 analytical, peer-reviewed papers, written by experts from academia, industry, and government, are divided into the following sections: Multiaxial Strength of Materials--addresses multiaxial strength, stress, and failure modes of materials. Multiaxial Deformation of Materials--investigates constitutive relationships and deformation behavior of materials under multiaxial loading conditions. Fatigue Life Prediction under Generic Multiaxial Loads--examines the challenging task of estimating fatigue life under general multiaxial loads. Fatigue Life Prediction under Specific Multiaxial Loads--describes biaxial and multiaxial fatigue and life estimation under combinations of cyclic loading conditions, such as axial tension/compression, bending, and torsion. Multiaxial Fatigue Life and Crack Growth Estimation--covers crack growth monitoring under cyclic mulitaxial loading conditions and determination of fatigue life. Multiaxial Experimental Techniques--explores state-of-the-art experimental methods to generate mulitaxial deformation and fatigue data to develop and verify both constitutive models used to describe the flow behavior of materials and fatigue life estimation models. Annotation Contains papers from a May 1999 symposium, describing state-of-the-art multiaxial testing techniques and analytical methods for characterizing fatigue and deformation behaviors of engineering materials. Papers are classified into sections on multiaxial strength of materials, multiaxial deformation, fatigue life prediction under generic multiaxial loads, fatigue life prediction under specific multiaxial loads, multiaxial fatigue life and crack growth estimation, and multiaxial experimental techniques. Some specific topics are biaxial strength testing of isotropic and anisotropic monoliths, generalization of energy-based multiaxial fatigue criteria to random loading, and cruciform specimens for in-plane biaxial fracture testing.
