Effective T-matrix of a cylinder filled with a random 2 dimensional particulate
K. K. Napal, P. S. Piva, A. L. Gower
When a wave, such as sound or light, scatters within a densely packed particulate, it can be rescattered many times between the particles, which is called multiple scattering. Mult…
The average transmitted wave in random particulate materials
Aris Karnezis, Paulo S. Piva, Art L. Gower
Microwave remote sensing is significantly altered when passing through clouds or dense ice. This phenomenon isn't unique to microwaves; for instance, ultrasound is also disrupted w…
Representing the stress and strain energy of elastic solids with initial stress and transverse texture anisotropy
Soumya Mukherjee, Michel Destrade, Artur L. Gower
Real-world solids, such as rocks, soft tissues, and engineering materials, are often under some form of stress. Most real materials are also, to some degree, anisotropic due to the…
A unified framework for linear thermo-visco-elastic wave propagation including the effects of stress-relaxation
Erik García Neefjes, David Nigro, Artur L. Gower +3
We present a unified framework for the study of wave propagation in homogeneous linear thermo-visco-elastic (TVE) continua, starting from conservation laws. In free-space such medi…
Effective Waves for Random Three-dimensional Particulate Materials
Artur Lewis Gower, Gerhard Kristensson
How do you take a reliable measurement of a material whose microstructure is random? When using wave scattering, the answer is often to take an ensemble average (average over time…
An ultrasonic measurement of stress in steel without calibration: the angled shear wave identity
Guo-Yang Li, Artur Lewis Gower, Michel Destrade
Measuring stress levels in loaded structures is crucial to assess and monitor their health, and to predict the length of their remaining structural life. However, measuring stress…
