Numerical modeling of mechanical behavior of clinch connections at breaking out and shearing

© The Authors, published by EDP Sciences, 2017. This article describes an approach to constructing the defining relationships between increment of true stresses and true deformations, with considering the contact interaction of elastoplastic deformed bodies among each other. Within the framework of finite element method, solving these problems in case of "breaking out" and "shearing" in the clinch joint, the stress fields in the zone of the clinch connection are defined, and recommendations are given for realizing the process of their creation

Modelling of deformation of underground tunnel lining, interacting with water-saturated soil

© Published under licence by IOP Publishing Ltd.Built finite element method of calculating the deformation of underground tunnel lining, interacting with dry and water-saturated soils. To simulate the interaction between the lining and soils environments, including physical and non-linear, a special "contact" finite element, which allows to consider all cases of interaction between the contacting surfaces. It solved a number of problems of deformation with the ground subway tunnel lining rings

Investigation of deformation of elements of three-dimensional reinforced concrete structures located in the soil, interacting with each other through rubber gaskets

© Published under licence by IOP Publishing Ltd. In work the technique of calculation of elements of three-dimensional reinforced concrete substructures located in a soil, interacting with each other through rubber linings is realized. To describe the interaction of deformable structures with the ground, special "semi-infinite" finite elements are used. A technique has been implemented that allows one to describe the contact interaction of three-dimensional structures by means of a special contact finite element with specific properties. The obtained numerical results are compared with the experimental data, their good agreement is noted

Investigation of the deformation of reinforced structures interacting with soils

© Published under licence by IOP Publishing Ltd. Within the framework of the proposed methodology for calculating the processes of interaction of elastic-plastic structures with soils of complex physical nature, based on the use of defining ratios connecting the increments of true stresses and deformations, a calculation is made of the stress-strain state of the lining of the underground tunnel and located in the immediate vicinity of the ventilator unit erecting over them a roadbed

On the results of experimental and numerical studies of the stress-strain state of concrete structures reinforced with pre-stressed polymer composite links

© 2019 IOP Publishing Ltd. As part of the work, experimental and numerical studies were carried out to assess the stress-strain state of concrete structures reinforced with polymer composite reinforcement. The experiment and numerical simulation obtained good consistency of the results. The research results showed that the pre-tension of links made of polymer composite reduces the deformability of the beams, by reducing the deflections by more than 4 times. Concrete structures, reinforced with pre-stressed strands of polymer composite, can be used in building structures for industrial and civil purposes, transport construction
