| Title of the article | Calculation of rod structures from reinforcing and ideally elastic-plastic materials |
| Abstract. | Problem statement. The purpose of this work is the development of a variational method for calculating a rod structure taking into account plastic deformations. It is assumed that when the rods are deformed, the relationship between the normal stresses and the longitudinal deformation of a rod is described by the diagram of a linearly strengthening body. Results. A variational method has been developed for calculating the rod structures from a reinforcing and ideally elastic-plastic material. The presented calculation technique is based on the separation of longitudinal deformation of a rod into two parts: elastic and plastic. The advantages of this approach consist in the fact that it is possible to carry out calculations for rod structures from a reinforced and ideal elastic-plastic material according to a single scheme. In particular, these advantages are manifested when determining the ultimate load for a system of perfectly elasto-plastic material. Conclusions. Using the described technique, various problems of bending and stretching-compression of rods for elasto-plastic deformations were solved. In this article presents the results of calculations of a statically indeterminate rod system. The obtained calculated data are in good agreement with known analytical solutions. |
