Nonlinear and Hysteretic Constitutive Models for Wave Propagation in Solid Media with Cracks and Corary loading histories are produced which are used as boundary conditions imposed at internal boundaries (cracks) in the material. As a result, we have developed a numerical toolbox capable of modeling elastic waves and vibrations in damaged samples or structures.

Nonlinear Ultrasonic Techniques for Material Characterization, late in the fatigue life (typically after 80%), while the material toughness and strength decreases gradually due to the microplasticity (dislocations) and associated change in the material’s microstructure. Starting from mechanics fundamentals, we first develop the theoretical equations of wave moInveterate 发表于 2025-3-25 15:09:22

Dynamic Acousto-Elastic Testing,or metals and polymers, the relative variation in ultrasound wave-speed is found between 10. and 10. per MPa of the applied stress. In cracked or granular media, contacts between the two lips of cracks or contacts between grains can greatly increase the variation in ultrasound wave-speed up to aboutGUILT 发表于 2025-3-26 07:54:23

Unlike other titles currently available, which treat nonlinearity as a physics problem and focus on different analytical derivations, the present volume emphasizes NDE applications over detailed analytical derivations.
