%X Double shear creep specimens were investigated by the transverse anisotropic finite element method, in order to study the multiaxial creep behavior of short fiber-reinforced metal matrix composites (MMCs). The creep behavior was dependent on orientations of the specimens and the transverse anisotropic parameters. The detailed evolution of the stress and strain in the double shear creep specimens shows that there is a steady stress state in the shear zone. The shear stress is near to the applied average shear stress, and independent of orientations of the specimens and the transverse anisotropicic parameters. The double shear specimen can provide a simple multiaxial stress state for MMCs. A procedure has been presented to evolve the parameters for the transversely anisotropic MMC materials, so that the double shear specimens can tested the transversely anisotropic material properties, some of which are difficult to get by the usual tensile specimens.
