 | This paper describes a study performed to experimentally investigate the constitutive behavior of silicon carbide whisker reinforced aluminum and to provide data for a companion material modelling study. The experimental program included measurement of material stress-strain curves, assessment of the acoustic emission response of the material, and examination of the material failure surfaces. The results of the mechanical tests showed that as the whisker content increases, stiffness, strength, and rate ... |

| This paper describes an analytical modeling effort designed to study the stress-strain behavior of silicon carbide whisker reinforced aluminum. The objective of the study was to develop an approximate method for predicting the stress-strain response of whisker reinforced metals as a function of constituent properties, whisker geometry, volume fraction, and extrusion ratio. The study utilized experimental results (described in a companion paper) for qualitative understanding of the material behavior and ... |

 | An analytical program was performed in which the thermo-visco-elastic response of a polymeric matrix on unidirectional composite properties were investigated. The fibers were assumed to be linear, elastic, temperature independent transversely isotropic materials while the matrix was modelled as a linear thermo-viscoelastic, isotropic material. The matrix was characterized as a thermorheologically complex material. Micromechanical analyses using the Composite Cylinder Assemblage and periodic hexagonal array were to model the unidirectional composite. ... |

|
| The second phase of an analytical effects to model the effects of low velocity transverse normal impact on laminated composite plates is described. The methodology consisted of a transient dynamics finite element analysis with capabilities for composite material characterization and stress predictions. A shear flexible plate bending element with material bending/extensional coupling capabilities was developed for this effort. The contact effects between the impacting mass and composite plate were modelled ... |
