Modeling the reinforced concrete shell with a protective structure

The results of the mathematical modeling and experimental studies for the stress-strain state of the annular section of the reinforced concrete shell with the protective structure are presented.  Computer simulation has been formulated as a stationary temperature problem.  The distribution of deformations and stresses is shown using the equations of the elastic theory.  A comparison of theoretical dependences on the results of experimental studies of physical models is given.

Applied Model of Assessment of Intensity of the Stressed Deformed State of Pipelines by Evaluation of Magnetic Anisotropy of Coercive Forces. Part 1

The problem of applied diagnostics, statistically rigorous by the proposed model analogue, running stressed-deformed state of the main (trunk) shell is studied by the method of magnetic coercimetria.
