A modification of the Signorini method for plane strains in an incompressible material |

| Abstract |
One of the methods for solving static problems of nonlinear elasticity
is the method of expansion of the solution into absolutely
convergent series with respect to a small parameter [1], suggested
by Signorini for the case where the specific strain energy is represented
by a polynomial of the strain tensor invariants. In the case of plane strain,
this method allows the application of the powerful means of the complex
analysis [2]. If the material is incompressible, the terms in the
expansion of the incompressibility condition (beginning from the second one)
are nonlinear and cannot be solved by Kolosov-Muskhelishvili potentials.
Hence, problems for displacements and mixed boundary-value problems contain
an equation to be satisfied in a plane domain. A method permitting one to take
into account the incompressibility conditions has been suggested in [3].
This method is based on the original statement of the plane elasticity
problem that has been formulated by L. A. Tolokonnikov [4] on the basis
of additional hypotheses as regards the relation between stresses and strains.
In the present paper, a modification of the Signorini method permitting
one to eliminate the incompressibility condition is suggested. Second-order
effects are singled out. An example of the solution of a problem for
displacements is given. |
