| Abstract |
An analytical-experimental method for identifying the material constants and functions in the constitutive relations of viscoelastic strain for homogeneous composite materials is proposed. The method is based on the minimization of the discrepancy between the results of numerical and experimental modeling of nonstationary deformation processes in shells of revolution made of the materials under study. The approach was tested and its adequacy was shown in problems of determining the rigidity and rheological characteristics of composite materials from the results of comparative analytical-experimental study of nonstationary deformation of spherical and cylindrical shells under impulsive loading. |
