Fig. 10. E ff ect of fuel linear power rating on the number of bonds broken in 0.08 mm node spacing outer monolith model.

Fig. 11. Broken bonds, top (red) and fibre pull-out strain (bottom) in outer monolith duplex isotropic and anisotropic models at a linear power rating of 27 kW m − 1 (0.08 mm node spacing).

At the same linear power rating, the inner monolith anisotropic model predicted partial delamination of the monolith-composite interface, while even at 36 kW m − 1 the isotropic model did not indicate any delamination as shown in Figure 12.
