metadata.value: Initial stress field acts significantly on the deformational process for porous structure. For accurate
  modeling of dynamics behavior of porous media taking into account initial stress field the corresponding
  mathematical model is essential. One of the common approaches for construction of mathematical model
  of dynamic behavior for porous media with considering initial state is linearization method. In current
  article the equations of longitudinal vibrations for poroelastic inhomogeneous body taking into account
  initial stress field are constructed on the basis of linearization for common deformation tensor. An influence
  of initial stress rate and Biot modulus rate on the dynamic behavior of media is analyzed. The problem for
  reconstruction of initial stress for poroelastic inhomogeneous column is considered based on application for
  genetic algorithms and nonlinear optimization method with the application of modern numerical software.
  The series of numerical experiments for reconstruction of various distribution laws of initial stress are
  performed using described methods. Refs 12. Figs 3.
