In this chapter, we describe software that analyzes multilayers that are at steady-state conditions with respect to time; in order to be applicable, the multilayers’ width must be much larger than the total stack thickness, such that one can neglect lateral gradients in the direction of the layers. The software can be used to determine the temperature distribution in the layers, the deformation (elongation and stretch) and stress distribution in the layers of the multilayer, or any submultilayers formed by delamination cracks. The software is based on one-dimensional heat transfer described in Section 2.6 and general multilayer mechanics framework outlined in Chapter 5. The software is applicable to any number of layers, and using this framework, the results can be used to compute the energy release rates for semi-infinite delamination cracks located at any location in the stack. The code associated with this chapter has been dubbed LayerSlayer (LS).
