The global behavior of a two phase composite consisting of linear elastic
reinforcements embedded in an elasto-plastic matrix is described by an
incremental Mori-Tanaka approach.
Using this formulation for calculating both the micro scale state of the
matrix material and the macro scale state of the composite, the overall
behavior of the composite can be evaluated for path dependent plastic
This approach is implemented into a finite element code, allowing structural
analyses of composite components.
