    • Noninvasive measurement of local stress inside soft materials with programmed shear waves 

      Zhang, Zhaoyi; Li, Guo-Yang; Jiang, Yuxuan; Zheng, Yang; Gower, Artur L.; Destrade, Michel; Cao, Yanping (American Association for the Advancement of Science, 2023-03-08)
      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 ...

    • Oblique wrinkles 

      Carfagna, M.; Destrade, Michel; Gower, Artur L.; Grillo, A. (The Royal Society Publishing, 2017-04-03)
      We prove theoretically that when a soft solid is subjected to an extreme deformation, wrinkles can form on its surface at an angle that is oblique to a principal direction of stretch. These oblique wrinkles occur for a ...

    • On residual stresses and homeostasis: an elastic theory of functional adaptation in living matter 

      Ciarletta, Pasquale; Destrade, Michel; Gower, Artur L. (Nature Publishing Group, 2016-04-26)
      Living matter can functionally adapt to external physical factors by developing internal tensions, easily revealed by cutting experiments. Nonetheless, residual stresses intrinsically have a complex spatial distribution, ...

    • Shear instability in skin tissue 

      Ciarletta, Pasquale; Destrade, Michel; Gower, Artur L. (Oxford University Press, 2013)
      We propose two toy-models to describe, predict and interpret the wrinkles appearing on the surface of skin when it is sheared. With the first model, we account for the lines of greatest tension present in human skin by ...

    • An ultrasonic method to measure stress without calibration: The angled shear wave identity. 

      Li, Guo-Yang; Gower, Artur L.; Destrade, Michel (Acoustical Society of America, 2020-12-03)
      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 ...
