Multiscale computational method for heat conduction problems of composite structures with diverse periodic configurations in different subdomains
It provides a multiscale method for engineers modeling heat conduction in complex composites, but the results are incremental and lack concrete performance metrics.
The study develops a second-order two-scale (SOTS) computational method for heat conduction in composite structures with varying periodic configurations across subdomains, demonstrating feasibility and effectiveness through numerical examples.
This study develops a novel multiscale computational method for heat conduction problems of composite structures with diverse periodic configurations in different subdomains. Firstly, the second-order two-scale (SOTS) solutions for these multiscale problems are successfully obtained based on asymptotic homogenization method. Then, the error analysis in the pointwise sense is given to illustrate the importance of developing SOTS solutions. Furthermore, the error estimates for the SOTS approximate solutions in the integral sense is presented. In addition, a SOTS numerical algorithm is proposed to effectively solve these problems based on finite element method. Finally, some numerical examples verify the feasibility and effectiveness of the SOTS numerical algorithm we proposed.
