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.
