Resumen de Strain gradient micromechanical modeling of substrate – supported crystalline microplates subjected to permanent in-plane and out-of-plane tractions
Amer Darvishvand, Asghar Zajkani
A benchmark study of small size plate structures exposed to permanent environmental interactions is presented. Micromechanically-motivated model is introduced for thin crystalline microplates under in-plane and out-of-plane excitations. Lower-order strain gradient plasticity (SGP) model is developed based on Chen-Wang Hardening law incorporating the influence of effective length scale. Since hardening parameter is a fundamental factor in physical descriptions of material, obtained results demonstrate the effect of length scale on the effective stresses due to in-plane and outof- plane excitations. While substrate – supported foundation is included, deflection and stress-strain curves are compared as well as the effect of variable tangent module.
