d5.05.01 Introduce a new non-linear law localized in DYNA_VIBRA

Summary:

DYNA_VIBRA makes it possible to perform a transient or harmonic response calculation.

This document describes the method for introducing a new localized non-linear distribution in this operator.

This possibility is only available on a transient calculation on a reduced basis called a modal basis by misnomer.
