Numerical modelling of the mechanical behaviour of Aluminosilicate Glass: A comparison between two simulation approaches

Abstract This paper presents a comparison between two numerical methods for modelling the mechanical and failure behaviour of aluminosilicate glass: Cohesive Elements Method (CEM) Finite Element coupled to Smooth Particle Hydrodynamics (FEM-SPH). The behaviours, provided by these approaches, are herein compared under i) quasi-static tests on material coupons, ii) dynamic (compressive tensile tests) also coupons iii) structural impact loading conditions in which ballistic perforation glass tiles due flat-nosed steel projectile considered. Both provide comparable results conditions, while more significant differences arise part, some limitations CEM shown.
