Non-invasive measurement of local stress inside soft materials with programmed shear waves
Zhaoyi Zhang, Guo-Yang Li, Yuxuan Jiang +4
Mechanical stresses in soft materials across different length scales play a fundamental role in understanding the function of biological systems and in the use of artificial materi…
Incremental dynamics of prestressed viscoelastic solids and its applications in shear wave elastography
Yuxuan Jiang, Guo-Yang Li, Zhaoyi Zhang +3
Shear wave elastography (SWE) is a promising imaging modality for mechanical characterization of tissues, offering biomarkers with potential for early and precise diagnosis. While…
SWENet: a physics-informed deep neural network (PINN) for shear wave elastography
Ziying Yin, Guo-Yang Li, Zhaoyi Zhang +2
Shear wave elastography (SWE) enables the measurement of elastic properties of soft materials, including soft tissues, in a non-invasive manner and finds broad applications in a va…
Non-destructive mapping of stress, strain and stiffness of thin elastically deformed materials
Guo-Yang Li, Artur L. Gower, Michel Destrade +1
Knowing the stress within a soft material is of fundamental interest to basic research and practical applications, such as soft matter devices, biomaterial engineering, and medical…
Supershear surface waves reveal prestress and anisotropy of soft materials
Guo-Yang Li, Xu Feng, Antoine Ramier +1
Surface waves play important roles in many fundamental and applied areas from seismic detection to material characterizations. Supershear surface waves with propagation speeds grea…
Elastic Cherenkov effects in transversely isotropic soft materials-I: Theoretical analysis, simulations and inverse method
Guo-Yang Li, Yang Zheng, Yanlin Liu +2
A body force concentrated at a point and moving at a high speed can induce shear-wave Mach cones in dusty-plasma crystals or soft materials, as observed experimentally and named th…
Guided waves in pre-stressed hyperelastic plates and tubes: Application to the ultrasound elastography of thin-walled soft materials
Guo-Yang Li, Qiong He, Robert Mangan +5
In vivo measurement of the mechanical properties of thin-walled soft tissues (e.g., mitral valve, artery and bladder) and in situ mechanical characterization of thin-walled artific…
Measuring the linear and nonlinear elastic properties of brain tissue with shear waves and inverse analysis
Yi Jiang, Guoyang Li, Lin-Xue Qian +3
We use supersonic shear wave imaging (SSI) technique to measure not only the linear but also the nonlinear elastic properties of brain matter. Here, we tested six porcine brains ex…
