摘要: This paper presents an integrated modelling approach for the post-thermal exposure flexural behaviour of glass fibre-reinforced (GFR) epoxy composites with/without flame retardants at both material and structural levels. numerical model incorporates outcomes from chemical kinetics heat-mass transfer analyses. The unit cell-based micro-mesoscopic meso-macroscopic mechanical models have been shown to accurately simulate GFR level. post-fire (e.g., thermally damaged by one-sided radiant heating) behaviours were numerically modelled using finite element (FE) predicted residual stiffness exposed different transient heating conditions are compared with experimentally-measured data in order validate while allowing its accuracy be assessed. good agreement between experimental demonstrates simulating bending composites.
