摘要

．提出了三维连续介质力学理论的混合型变分方法。应用该方法分析了非均质各向异性弹塑性体在有限变形中子通量作用下蠕变过程中的应力-应变状态，同时考虑了损伤性和扩散。本文对复合材料在非均质介质中不同相夹杂物的形成和证明定理作了修正。

Mixed-type variational principle for creep problems considering the aggressiveness of external fields

. A mixed type variational method for the three-dimensional theory of continuum mechanics has been developed. It is applied for the analysis of the stress-strain state (SSS) of inhomogeneous anisotropic elastoplastic bodies during creep under the action of neutron fluxes at finite deformations with consideration of damageability and diffusion. A modification of the formed and proved theorem for the case of composite material when different phase inclusions in heterogeneous medium are clearly expressed is given in the paper.

期刊介绍： Engineering Transactions (formerly Rozprawy Inżynierskie) is a refereed international journal founded in 1952. The journal promotes research and practice in engineering science and provides a forum for interdisciplinary publications combining mechanics with: Material science, Mechatronics, Biomechanics and Biotechnologies, Environmental science, Photonics, Information technologies, Other engineering applications. The journal publishes original papers covering a broad area of research activities including: experimental and hybrid techniques, analytical and numerical approaches. Review articles and special issues are also welcome. Following long tradition, all articles are peer reviewed and our expert referees ensure that the papers accepted for publication comply with high scientific standards. Engineering Transactions is a quarterly journal intended to be interesting and useful for the researchers and practitioners in academic and industrial communities.
