Solution of a paradox related to the rigid bar pull-out problem in standard elasticity
Rezaei, Nasrin; Barchiesi, Emilio; Timofeev, Dmitry; Tran, C. Anthony; Misra, Anil; Placidi, Luca (Elsevier, 2022)Acceso restringidoThis paper aims at modeling pull-out tests of a reinforcement bar from a concrete matrix. The considered system is an elastic cylinder, within which is embedded a rigid bar placed along the central axis. The pull-out test ... -
Two-Dimensional Analysis of Size Effects in Strain-Gradient Granular Solids with Damage-Induced Anisotropy Evolution
Maksimov, Valerii; Barchiesi, Emilio; Misra, Anil; Placidi, Luca; Timofeev, Dmitry (American Society of Civil Engineers (ASCE), 2021)Acceso restringidoWe analyze in two dimensions the mechanical behavior of materials with granular microstructures modeled by means of a variationally formulated strain-gradient continuum approach based on micromechanics and show that it can ...
