DOI: 10.1002/adom.202501338
Abstract: Conventional nonpolar nematic liquid crystals, widely known for their successful display applications, are not well suited for fast electro‐optical switching because of the slow (milliseconds) field‐off relaxation of the director. In this work, sub‐microsecond field‐on… read more here.

DOI: 10.1007/s00161-019-00755-5
Abstract: In this paper, we propose a canonical variational framework for rate-independent phenomenological geometrically linear gradient plasticity with plastic spin. The model combines the additive decomposition of the total distortion into non-symmetric elastic and plastic distortions,… read more here.

DOI: 10.1007/s00603-020-02147-7
Abstract: Several experimental studies, carried out on anisotropic rocks, have evidenced that even though strains, due to isotropic loading and/or internal fluid pressure, are strongly anisotropic, the resulting Biot’s tensor is almost isotropic. Those results were… read more here.
