Measuring the in-plane mechanical stress in a taut membrane is challenging, but fundamental to basic research and practical applications, from engineering to tissues. Here, the authors propose an accurate measurement technique of the in-plane stress

Mechanical stresses across different length scales play a fundamental role in understanding biological systems’ functions and engineering soft machines and devices. However, it is challenging to noninvasively probe local mechanical stresses in situ

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 or space). By ensemble averaging we can calculate the average scattere

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 their microstructure, a characteristic often called the ‘texture anisotr

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 media admit two thermo-compressional modes and a shear mode. We provide as

Measuring stress levels in loaded structures is crucial to assess and monitor structure health and to predict the length of remaining structural life. Many ultrasonic methods are able to accurately predict in-plane stresses inside a controlled labora

International audience; Many interesting shapes appearing in the biological world are formed by the onset of mechanical instability. In this work we consider how the build-up of residual stress can cause a solid to buckle. In all past studies a ficti

We present examples of body wave and surface wave propagation in deformed solids where the slowest and the fastest waves do not travel along the directions of least and greatest stretch, respectively. These results run counter to commonly accepted th

Suppose we measure the scattered field from a material with an assortment of randomly placed particles of different sizes. To get a repeatable measurement, we may need to perform the experiment many times and average over time (or space). This talk f

Effective medium theory aims to describe a complex inhomogeneous material in terms of a few important macroscopic parameters. To characterize wave propagation through an inhomogeneous material, the most crucial parameter is the effective wavenumber .
