Abstract:Present a kind of model which can analyze the transient heat conduction of linear heterogeneous material to predict and evaluate the effective properties of macroscopic temperature equivalent behavior. Based on adaptive algorithm in time domain, the transient heat conduction equation can be expanded in time domain. Combining with the asymptotic expansion homogenization (AHE) technique the recursion scheme of equivalent heat conduction equation is obtained. Finally, transient temperature field calculation equivalent model can be acquired by the finite element method. The calculation error can be avoided through the adaptive computation when the size of time step changes. In numerical examples the calculation results of equivalent analysis and the heterogeneous solutions based on ANSYS are compared, and satisfactory results are achieved.
