Wave Propagation in Stressed Composites
The Journal of the Acoustical Society of America, 1996 The performance of high-temperature composites can be significantly affected by the presence of residual stresses. These stresses arise due to the mismatch of thermal expansion coefficients between matrix and fibers during cooling from fabrication temperature to room temperature.

Prediction of the modulus of elasticity of Eucalyptus grandis through two nondestructive techniques
Floresta e AmbienteThe present study aimed to estimate the modulus of elasticity (MOE) at static bending of Rose gum (Eucalyptus grandis) heartwood and sapwood through two nondestructive techniques: ultrasound and stress wave.

Changes in wave climate over the northwest European shelf seas during the last 12,000 years
, 2009 Because of the depth attenuation of wave orbital velocity, wave-induced bed shear stress is much more sensitive to changes in total water depth than tidal-induced bed shear stress.

Research on the Vibration and Wave Propagation in Ship-Borne Tethered UAV Using Stress Wave Method
Drones, 2022 To investigate the vibration behavior of ship-borne tethered UAVs under taut–slack conditions, the Hamilton principle is used to establish the three-dimensional dynamic equations of the ship-borne tethered UAVs while taking into account geometric ...

A Study of Static and Dynamic Mechanical Behavior of the Substrate in Ultrasonic Consolidation [PDF]
, 2006 A new 2-D FEM model is developed for a fundamental study of the time dependent mechanical behavior of the substrate in ultrasonic consolidation. The simulation shows that for a given vibration condition, the amplitude of contact friction stress and ...

Propagating Stress Waves During Epithelial Expansion
Physical Review Letters, 2015 Coordinated motion of cell monolayers during epithelial wound healing and tissue morphogenesis involves mechanical stress generation. Here we propose a model for the dynamics of epithelial expansion that couples mechanical deformations in the tissue to contractile activity and polarization in the cells.

Numerical simulation of stress wave propagation in joint rock specimens with cavity defects
Frontiers in Earth Science, 2022 The process of crack initiation, propagation, and coalescence is the essential cause of rock failure. A three-dimensional numerical model based on microscopic damage mechanics is adopted to simulate the failure process and acoustic emissions (AEs) of a ...

Relaxation of curvature induced elastic stress by the Asaro-Tiller-Grinfeld instability
, 2015 A two-dimensional crystal on the surface of a sphere experiences elastic stress due to the incompatibility of the crystal axes and the curvature. A common mechanism to relax elastic stress is the Asaro-Tiller-Grinfeld (ATG) instability.
