A finite element model for the fire-performance of GRP panels including variable thermal properties

Finite element modelling of fibre reinforced polymer sandwich panels exposed to heat

“…In agreement with Reference [1] (but not with the models of References [3,4], where the mixing is treated on the level of mass densities of the resin and the fibre reinforcement) the composition of the solid phase is described using a mixture equation with F being the fraction of the current mass density of the resin in the solid phase and the initial mass density of the resin in the virgin material.…”

“…Looyeh et al [3], and Looyeh and Bettess [4] have used a variation on Henderson's model, with a numerical solution obtained with a Galerkin finite element method. In this work, we wish to explore the issue of the proper formulation of the finite element discretization, with particular attention devoted to the formulation of the time stepping and update of the various quantities in the model, and identification of the requisite input parameters for the model.…”

Structural integrity of polymer matrix composite panels in fire

“…Past research for the thermal model includes verification with experiments, investigation of composites' thermal properties, and efficient numerical schemes. Henderson et al (1985), Henderson and Wiecek (1987) and Wu et al (1993) employed the finite difference schemes for the thermal model; Looyeh et al (1997), Looyeh and Bettess (1998) and Krysl et al (2004) described finite element schemes. Gibson et al (1995) employed the thermal model to study failure mechanisms for specimens in one-sided fire exposure.…”

Modeling and simulation of wetted porous thermal barriers operating under high temperature or high heat flux

“…Other studies concerning the use of thermal protections under fire conditions can be found [5][6][7][8][9][10], some of them characterizing the details of the layered medium, which can include a inside air gap, and thermal radiation heat transfer. Some other studies, just to cite a few, are devoted primarily to questions related to the skin injury [4,11] or to the degradation of the involved materials as well as to the heat and mass transfer aspects of the barriers exposed to fire [12][13][14][15][16][17][18][19]. Special attention has been given to concrete behavior and the possibility of its damage under intense thermal conditions, and in particular under fire conditions [20][21][22][23][24][25].…”
