Abstract:
The paper presents approximate models of deformation
for an inhomogeneous elastic strip. Approximate models reflect the
distribution features of the inhomogeneous structure properties
over the thickness. The models are based on hypotheses about the
nature of the change in the components of the displacement field,
which allows to consider arbitrary laws of heterogeneity:
continuous, as well as discontinuous or having a strong gradient.
Solutions of the contact problem for different inhomogeneity laws
are constructed. Comparative analysis of the models is carried
out. The results of the solutions are compared with the solution
based on the FE model.
