| dc.description.abstract | A phenomenological and parametric study was conducted to assess the effect of thermal residual stresses on the stressstrain response of a discontinuous fiber-reinforced metalmatrix composite in tensile and compressive loading. The material chosen for this investigation was the SiC-whisker reinforced Al 6061. The difference between composite flow behavior in tension and compression, as well as the effects of volume fraction, fiber aspect ratio and fiber spacing were analyzed within the framework of axisymmetric finite-element models to determine the overall constituative response of the composite and to solve for local field quantities in the fiber and the matrix. The composite was modeled as a periodic array of cylindrical fibers with perfect interfacial bonding and complete fiber alignment with the tensile/compressive axis. It was found that the presence of residual stresses affected the stress-strain behavior of the composite by influencing the load transfer characteristics between the matrix and the fiber as well as the initiation and growth of the plastic deformation in the matrix. | en_US |
