Using the apparatus of integral transformations, the problem is reduced to a system of Fredholm integral equations of the first kind with a logarithmic singularity. Using the Bubnov-Galorkin method and using recurrent relations to calculate the integrals, a numerical-analytical method was developed, which allows to study the critical parameters of failure (critical stresses and critical shortenings).    Product Description popup.authors popup.nrat_date 2021-02-25 Close
