Higher-Order Modules in the Equations of Dynamics of a Prestressed Elastic Solid

Аннотация

In terms of the reference configuration, the linearization of the equations of nonlinear mechanics of an initially isotropic elastic solid (IIES) is carried out in the vicinity of a. certain prestressed equilibrium state. In this case, we used a. special representation of the elastic potential in terms of algebraic invariants of the Cauchy-Green strain tensor containing moduli of higher orders. Linearized defining relations and equations of motion are constructed that take into account the nonlinear effect of the initial deformations on the properties of the IIES.
