Stress-strain state of microinhomogeneous cracked plates

Materials Science, 1996
For the model of a microinhomogeneous body, we determine the distribution of efficient (averaged over microvolumes) components of the stress tensor and study the effects of the parameters of rigidity of the material in micro- and macrovolumes, the dimensions of the selected volume, and the angle of application of the external load on the value of ...

Stress-strain state of unsealed gravity dams

Hydrotechnical Construction, 1985
Current methods for calculating dams permit investigating the stress-strain state of such structures; however, so far a lack of confidence in the possibility of a calculated substantiation of the reliability of high unsealed dams is sometimes encountered.

Stress-strain state of fault models analysis

Mining Industry Journal (Gornay Promishlennost), 2023
The paper analyzes the procedure of creating three-dimensional models of discontinuous and tectonic faults for numerical modeling problems using the finite element method. A number of uncertainties arise in the geomechanical analysis of the stress-strain state of faults due to the choice of the type of their computational geological model, e.g.

Stress-strain state of elastomeric axisymmetric shells

Soviet Applied Mechanics, 1988
Summary: Known approaches to the investigation of large deformations of momentless shells of revolution lead to significantly nonlinear differential equations, whose integration entails considerable difficulty. The present work outlines a formulation of the problem with a reduction in the order of the resolving equations, which allows the stress-strain

Stress-strain state of mechanical rebar couplings

AIP Conference Proceedings, 2016
Mechanical rebar couplers are preferable in the advanced building construction and structural design of anti-seismic elements. The paper presents destructive inspection techniques used to investigate stress fields (tensile and compressive) and deformation curves for mechanical rebar splicing. The properties of mechanical rebar splicing are investigated

Numerical Experiments on Helicoids Stress-Strain State

2019
Helicoidal surfaces are widely used in various structures and their elements, especially in mechanical engineering, as well as in civil engineering and architecture. However there are still different classifications in both mathematical and engineering fields, and the general types of these surfaces are not completely investigated. In this paper, there

Stress-strain state of waste-storage dam

Journal of Mining Science, 1998
inaccurate for the internal problems, i.e., for the dam (as well as adjacent regions of the same size as the boundary element); it is also difficult to take the diversity of properties of the dam materials into account; b) in FEM, it is necessary to determine the load vector for all points on the basis of theoretical dependences (for example, taking ...
