| Abstract: | An anisotropic medium is considered in which, upon loading, scattered microdamages accumulate giving rise to nonlinear and
residual strains. The damage at a point of the medium is characterized by a scalar function on a unit sphere, referred to
as the damage function. This function is approximated by a fourth-rank tensor used for specifying the relation between the
increments of strains and stresses. The calculation dependences are presented in detail for a unidirectional composite, which
is taken to be a homogeneous transversely isotropic medium. Determination of the unknown constants is illustrated by the example
of an actual fiberglass plastic.
