The present paper develops a version of a compound hierarchical model of materials, which implements a possibility of representing a complex process of the development of interrelated deformation effects in the form of a succession of formally independent elementary acts described by the related particular models of irradiation-induced swelling, plasticity, thermal and irradiation creep. In describing actual processes, the interaction and mutual effect of such elementary acts are taken into account on the top level of the compound model, providing for the successive initialization of the particular models and updating their constituent parameters (stresses and parameters characterizing the history of elastoviscoplastic deformation of materials). Using the example of steel Kh16N11KM3, a number of benchmark problems have been analyzed. The obtained results show that the developed software product can be effectively used for analyzing problems of deformation of structures under thermal-radiation effects. The process of deformation of a model of a shell ring of a fast-neutron reactor reflector made of steel Kh16N11M3 in the conditions of spatial thermal-radiation effects has been numerically analyzed.

本文开发了一种材料的复合层次模型的版本，该版本以一种由相关的特定辐射模型描述的一系列形式独立的基本行为的形式实现了表示相关变形效应发展的复杂过程的可能性。引起膨胀，可塑性，热和辐射蠕变。在描述实际过程时，在复合模型的顶层考虑了这些基本行为的相互作用和相互影响，提供了特定模型的连续初始化并更新了它们的组成参数（表征弹性粘塑性历史的应力和参数）材料变形）。以Kh16N11KM3钢为例，分析了许多基准问题。所得结果表明，所开发的软件产品可以有效地用于分析结构在热辐射作用下的变形问题。在空间热辐射效应的条件下，对由Kh16N11M3钢制成的快中子反应堆反射器的壳环模型的变形过程进行了数值分析。
