Abstract: Abstract In this paper we deal with the determination of the strain gradient elasticity coefficients of composite material in the framework of the homogenization methods. Particularly we aim to eliminate the persistence of the strain… read more here.

Abstract: We propose a linearized model for isotropic damage with strain-gradient effects in the small-strain isothermal regime. We account for pressure-confinement effects induced by spatial variations of volume changes, which might locally determine a self-healing-type behavior.… read more here.
