This article divulges the outcomes of theoretical investigations into non-uniformly damaged reinforced concrete beams, employing the LIRA-FEM software suite. The manifestation of defects and damages poses operational risks for buildings and structures. The objective of this study is to scrutinize the consequences of irregular damage occurrence in reinforced concrete beams, holding significant practical relevance for the determination of the stress-strain condition in reinforced concrete elements.

Описано спосіб розрахунку теплофізичних характеристик композитних матеріалів зі складною внутрішньою структурою на основі дискретної моделі, що будується за методом теплоелектричних аналогій.

This paper consider the method of calculation the thermophysical characteristics of composite materials with complex internal structure based on the discrete model that is constructed by the method of thermal-electric analogies.

The thermoregulation of human female body is influenced by hormonal and physiological changes in the body during the menstrual cycle.  The fluctuation of estrogen and progesterone hormones, release in the follicular phase and the luteal phase of menstrual cycle, respectively play an important role in the growth of breast ducts and lobules (milk glands).  The imbalance of these hormones causes breast tumors/cysts.  The body core temperature, blood perfusion and metabolism rate are higher in the luteal phase than the follicular phase of menstrual cycle.  In the present work, a tumor/cyst is a

Problems of determination of optimal geometric and constructive parameters of long-length structures are presented. For example, a longitudinal profile of a complicated section is adopted, its components of the stress state and its own oscillation frequencies are determined. The choice of optimal profile parameters is made for the implementation of structures with minimum equivalent stresses, as well as for ensuring maximum dynamic stiffness.
