摘要

摘要研究考虑了采用三维技术制造的金属多孔复合材料以及具有遗传松弛或蠕变核心的分散强化聚合物复合材料中的应力和应变之间的关系。通过拉普拉斯变换应用 Volterra 匹配原理，在图像中计算出复合材料的有效粘弹特性。这些特性的原始数据是通过使用标准运算微积分方法进行反变换获得的。对于带有聚合物基体的复合材料，则使用积分算子的 Yu.N. Rabotnov 方法。因此，获得了金属复合材料的有效应力松弛特性。对于聚合物复合材料，得到了单轴负载下蠕变的有效规律。蠕变的理论结果与类似的实验结果进行了比较。

Effective Viscoelastic Properties of Metal and Polymer Composites

Abstract

The relationships between stresses and strains in metal porous composites manufactured using 3D technologies, as well as in dispersion-strengthened polymer composites with a hereditary relaxation or creep core, are considered. By applying the Volterra matching principle using the Laplace transform, the effective viscoelastic properties of the composite are calculated in the images. The originals of these characteristics were obtained by inverse transformations using the standard operational calculus method. For composites with a polymer matrix, the Yu.N. Rabotnov method of integral operators is used. As a result, effective stress relaxation characteristics were obtained for metal composites. For polymer composites, an effective law of creep under uniaxial loading was obtained. The theoretical results on creep were compared with similar experimental results.

期刊介绍： Steel in Translation is a journal that represents a selection of translated articles from two Russian metallurgical journals: Stal’ and Izvestiya Vysshikh Uchebnykh Zavedenii. Chernaya Metallurgiya . Steel in Translation covers new developments in blast furnaces, steelmaking, rolled products, tubes, and metal manufacturing as well as unconventional methods of metallurgy and conservation of resources. Papers in materials science and relevant commercial applications make up a considerable portion of the journal’s contents. There is an emphasis on metal quality and cost effectiveness of metal production and treatment.
