    • Non-destructive mapping of stress and strain in soft thin films through sound waves 

      Li, Guo-Yang; Gower, Artur L.; Destrade, Michel; Yun, Seok-Hyun (Nature Research, 2022-09-17)
      Measuring the in-plane mechanical stress in a taut membrane is challenging, especially if its material parameters are unknown or altered by the stress. Yet being able to measure the stress is of fundamental interest to ...

    • 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, ...

    • Representing the stress and strain energy of elastic solids with initial stress and transverse texture anisotropy. 

      Mukherjee, Soumya; Destrade, Michel; Gower, Artur L. (The Royal Society, 2022-10-12)
      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 ...

    • 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 ...
