Abstract

This work discusses the effective specific heat of multi-phase composites. A new formulation is provided using property contribution tensors and the specific heat contribution tensor (scalar) is derived in the framework of the Non-interaction, the Mori–Tanaka, and the Maxwell effective field methods (EFMs). The novel formulas are presented for the general case of an anisotropic matrix with anisotropic inhomogeneities of diverse shapes and orientations. Two limited cases of particulate and fibrous two-phase composites are discussed and the results of the novel formulation are compared to results of experiments and finite element models, and exhibit a great agreement.

多相复合材料有效比热的有效场法研究

本文讨论了多相复合材料的有效比热。在非相互作用、Mori-Tanaka和Maxwell有效场方法（efm）的框架下，利用性质贡献张量给出了一个新的公式，并导出了比热贡献张量（标量）。对于具有不同形状和取向的各向异性不均匀性的各向异性矩阵，给出了新的计算公式。讨论了颗粒和纤维两相复合材料的两种极限情况，并将新配方的结果与实验结果和有限元模型的结果进行了比较，结果显示出很大的一致性。

期刊介绍： The International Journal of Solids and Structures has as its objective the publication and dissemination of original research in Mechanics of Solids and Structures as a field of Applied Science and Engineering. It fosters thus the exchange of ideas among workers in different parts of the world and also among workers who emphasize different aspects of the foundations and applications of the field. Standing as it does at the cross-roads of Materials Science, Life Sciences, Mathematics, Physics and Engineering Design, the Mechanics of Solids and Structures is experiencing considerable growth as a result of recent technological advances. The Journal, by providing an international medium of communication, is encouraging this growth and is encompassing all aspects of the field from the more classical problems of structural analysis to mechanics of solids continually interacting with other media and including fracture, flow, wave propagation, heat transfer, thermal effects in solids, optimum design methods, model analysis, structural topology and numerical techniques. Interest extends to both inorganic and organic solids and structures.
