Stress-strain state of bending reinforced beams with cracks
Инженерно-строительный журнал, 2020 The work is dealing with studying the stress-strain state of bending pre-stressed concrete beams with cracks. The problems of determining preliminary stresses in a reinforced concrete element, determining the moment of crack formation, and determining ...

Isometric deformations of surfaces of translation [PDF]
Math. Mech. Compl. Sys. 12 (2024) 1-17, 2023 A \emph{surface of translation} is a sum $(u,v)\mapsto\gt\alpha(u)+\gt\beta(v)$ of two space curves: a \emph{path} $\gt\alpha$ and a \emph{profile} $\gt\beta$. A fundamental problem of differential geometry and shell theory is to determine the ways in which surfaces deform isometrically, i.e., by bending without stretching.

To bend or not to bend, the dilemma of multiple bonds
Physical Chemistry Chemical Physics, 2019 Beyond the second row of the periodic table, the nature of the multiple bonds between main group elements remains yet elusive. At a closer look they turn to be more similar to their second-row counterparts than previously believed.

Dense Gas, Massive Stars, and Ionising Radiation: Simulating Stellar Feedback in Spiral-Arm Molecular Clouds [PDF]
, 2021 Star formation (SF) has been continuous since the Universe was 200 million years old. It occurs in the interstellar medium (ISM) – the gas and dust between stars within galaxies.

Ultra-thin silicon-on-insulator waveguide bend based on truncated Eaton lens implemented by varying the guiding layer thickness [PDF]
, 2020 Silicon-on-insulator (SOI) waveguides with different geometries have been employed to design various integrated optical components. Reducing the bending radius of the SOI waveguides with low bending loss is essential in minimizing the footprint of light-wave circuits. The propagating mode is less confined in the core of the ultra-thin SOI waveguide and

THE EFFECT OF ROTATING-BENDING FATIGUE ON HIGH-DENSITY POLYETHYLENE [PDF]
Romanian Journal of Petroleum & Gas Technology, 2022 External factors, such as main stresses, frequency of the loading, shape and history of loading (hysteresis) have an important effect on the fatigue behavior of high-density polyethylene.
