Regularities of deformation of elastic massifs
Journal Title: Технічна механіка, Техническая механика, Technical Mechanics - Year 2015, Vol 3, Issue 3
Abstract
The analysis of the existing solutions for the elasticity theory is demonstration of their serious disadvantages resulted from the application of imperfect physical dependences. In order to eliminate this problem and to simplify the solution process, it is proposed to divide complete deformations into two independent types: volume deformations and deformations of pure shears. A full range of deformations of each type is determined separately, according to their regularities of deformations. These regularities are associated with various forms of the influence of the potential pressure function, which represents a stressed state of an elastic massif and is de-termined by given limited conditions. As a result, the disadvantages of solutions are eliminated, the range of problems having exact analytical solutions extends, and at the same time, derivation of these solutions is simpli-fied.
