SLIP_INTERACTION#
Description#
The SLIP_INTERACTION object is used to model the inter-system
hardening of the isotropic variable for single crystal models. In the
absence of this option, only self-hardening is taken into account
(h1=1. and all other interaction parameters equal 0.). For
each crystal potential, the maximum number of interaction parameters is
given in the section on <CRYSTAL_ORIENTATION>. As an
example, the hardening matrix describing the inter-system hardening
for octahedral slip systems is shown at the end of this section.
Note: hardening between different crystal potentials (for instance between cubic and octahedral systems) can be taken into account through the INTERACTION object.
Syntax#
The following models are implemented for slip interaction in single crystals.

standard Zebulon form. |
slipThis is the “standard” Zebulon format for full slip interactions described by []. The coupled radius \(R'_i\) for system \(i\) is
(482)#\[R'_i = R_0 + \sum_{k=1}^n h_{ik} \left( R_k-R_0 \right) ,\]where \(R_k\) is the radius of slip system \(k\) as calculated from the
*isotropicvariable option (e.g. \(R_0 + Q(1-e^{-bv})\)).
