Book Description
The Total Strain Version of the method of Strainrange Partitioning was used as the basis for modeling the thermomechanical fatigue resistance of the matrix material of the metal matrix composite, SCS-6/Ti-15-3. As prescribed by the model, the resistance was assessed through the use of bithermal creep-fatigue experiments. Bithermal temperatures of 205 and 427°C were imposed. A minimal number of strain limit-controlled, in-phase PP (pure fatigue, no creep) and CP (tensile creep) as well as out-of-phase PP (pure fatigue, no creep) and PC (compressive creep) experiments were conducted on conventional, axially-loaded, cylindrical-bar specimens. Inelastic strain range versus cyclic life curves for each of the Strainrange Partitioning bithermal cycles were evaluated and found to be nominally coincident. Cyclic elastic strain range versus inelastic strain range curves as well as elastic strain range versus life curves were documented for pure-fatigue and creep-fatigue conditions. The time-dependencies of these relationships were calibrated with the available data. These results enable the construction of total strain range versus fatigue life curves for thermomechanical fatigue for in- and out-of-phasing and for any arbitrary creep-time per cycle. Results are pplicable to the cyclic life prediction of metal matrix composites using the Ti-15-3 matrix material.

Book Description
Metal Matrix Composites: Thermomechanical Behavior discusses metal matrix composites, elaborating on that consists of two phases—fiber as reinforcement and metal as matrix. This book focuses on polymer matrix composites, including topics in metal matrix composites ranging from processing to fracture mechanics. The three basic types of composite materials—dispersion-strengthened, particle-reinforced, and fiber (whisker)-reinforced, are also described in detail. Dispersion-strengthened is characterized by a microstructure consisting of an elemental matrix within which fine particles are uniformly dispersed, while particle-reinforced is indicated by dispersed particles of greater than 1.0 μm diameter with a volume fraction of 5 to 40%. Fiber (whisker)-reinforced provides a distinguishing microstructural feature of fiber-reinforced materials, such as that the reinforcing fiber has one long dimension, while the reinforcing particles of the other two types do not. This publication serves as a reference data book to students and researchers aiming to acquire knowledge of the thermomechanical behavior of metal matrix composites.

Book Description
The nonlinear behavior of a high-temperature metal-matrix composite (HT-MMC) was simulated by using the metal matrix composite analyzer (METCAN) computer code. The simulation started with the fabrication process, proceeded to thermomechanical cyclic loading, and ended with the application of a monotonic load. Classical laminate theory and composite micromechanics and macromechanics are used in METCAN, along with a multifactor interaction model for the constituents behavior. The simulation of the stress-strain behavior from the macromechanical and the micromechanical points of view, as well as the initiation and final failure of the constituents and the plies in the composite, were examined in detail. It was shown that, when the fibers and the matrix were perfectly bonded, the fracture started in the matrix and then propagated with increasing load to the fibers. After the fibers fractured, the composite lost its capacity to carry additional load and fractured. Gotsis, Pascal K. Glenn Research Center RTOP 510-10-01...
