High temperature metal matrix composites offer great potential for use in advanced aerospace structural applications. The realization of this potential however, requires
concurrent developments in
- a technology base for fabricating high temperature metal matrix composite structural components,
- experimental techniques for measuring
their thermal and mechanical characteristics, and
- computational methods to predict their behavior.
METCAN (METal matrix Composite ANalyzer) is a computer program
developed to predict this behavior. METCAN can be used to computationally simulate the non-linear behavior of high temperature metal matrix composites (HT-MMC),
thus allowing the potential payoff for the specific application to be assessed. It provides a comprehensive analysis of composite thermal and mechanical performance.
METCAN treats material nonlinearity at the constituent (fiber, matrix, and interphase) level, where the behavior of each constituent is modeled accounting for
time-temperature-stress dependence. The composite properties are synthesized from the constituent instantaneous properties by making use of composite micromechanics
and macromechanics. Factors which affect the behavior of the composite properties include the fabrication process variables, the fiber and matrix properties, the bonding
between the fiber and matrix and/or the properties of the interphase between the fiber and matrix.
The METCAN simulation is performed as point-wise analysis and produces composite properties which are readily incorporated into a finite element code to perform a
global structural analysis. After the global structural analysis is performed, METCAN decomposes the composite properties back into the localized response at the various
levels of the simulation. At this point the constituent properties are updated and the next iteration in the analysis is initiated. This cyclic procedure is referred to as the
integrated approach to metal matrix composite analysis.
METCAN-PC carries the NASA case number LEW-15711. It was originally released as part of the COSMIC collection.
