Detailed Description

Base abstract class representing cross section in finite element mesh.

The main idea, why cross section has been introduced, is to hide all details of cross section description from particular element. Generally elements do not communicate directly with material but communicate through cross section interface, which therefore can perform necessary integration (for example over layers of fibers).

The cross section returns properties like thickness and area.

The derived classes are supposed to be base cross section classes for particular type of analysis. They should declare general interface methods necessary.

In particular cross section implementation, where is necessary to perform integration over cross section volume (over layers, fibers, ...) and therefore generally one must keep complete load history in these integration points, the concept of master-slave integration points should be used.

Integration point generally can contain list of slave integration points therefore is called as master point. Slaves are used for example to implement layered or fibered cross sections by cross section class. Then in one "macro" master Gauss point, cross section creates few slaves (one per layer) and puts them into master list. When cross sections completes requests for particular master integration point, it performs integration over layers. It therefore calls material class for each layer, sending corresponding slave as parameter and integrates results.

Nonzero if successful.
