| Abstract |
The analysis of the sensitivity of the deformation parameters to perturbations
of material functions plays an important role (in both academic and applied
aspects) in continuum mechanics, especially in problems with mixed boundary
conditions [1]. The statement of the problem for an inhomogeneous continuous
medium in the case of Eulerian description of the motion involves, in
particular, the determination of the law of motion of Lagrangian particles
along their trajectories and the inversion of this law. If at the initial time
instant the difference of the material functions in an inhomogeneous material
from some familiar distributions (e.g., constant distributions) is small, one
can use the asymptotic method of [2]. This method is tested on the problem of
compression of a thin perfectly plastic layer weakly inhomogeneous with respect
to the yield strength by rigid plates. As the basic process we choose the
quasistatic deformation of a homogeneous medium. This process corresponds to
Prandtl's solution. A linear initial-boundary value problem is formulated for
the perturbations. For some particular cases of the initial inhomogeneity this
problem can be solved analytically. |
