Embodiment Construction
[0077] The specific implementation of the present invention will be further described below in conjunction with the accompanying drawings and examples.
[0078] Such as figure 1 As shown, there are 5 main processes in this embodiment:
[0079] 1 Homogenization analysis
[0080] Assuming a homogeneous isotropic matrix (M 1 ) and particles (M 2 ) two-phase composite material M composed of materials to establish a corresponding mesoscopic homogenization model, such as figure 1 As shown, its reference shape is R 0 , the thermal constitutive equation is
[0081] q=-K·▽θ(1)
[0082] Among them, q represents the heat flux, K represents the thermal conductivity tensor, θ represents the temperature change, and ▽θ represents the temperature gradient. A thermal boundary value problem for this heterogeneous material M is: Solve the temperature function θ(X,t) so that the following equation in R 0 established on
