摘要

Creep phenomenon may be hazardous for mechanical and electromechanical composites, connections, networks and devices. Recently, the metal matrix composites (MMC's) are generally employed to design the mechanical systems and devices due to their advantages. Therefore, analysis of the creep behavior is essential and significant for safe designing the fibrous composite devices. Different theoretical method is presented for analyzing the second stage creep of the short fiber composites subjected to axial load using nonlinear displacement functions. Behavior of crept matrix is described by an exponential creep law, whilst the fibers behave elastically in general. The major plan of this research work is prediction of the creeping response and behavior in the fibrous composites for preventing unwanted events, over and above, controlling the creep deformation rate theoretically and numerically. Newly, the creep analysis of the fibrous composites is one of the important challenges in various applied sciences and technologies. MMC's contain a lot of advantages such as excellent conductivities. Using the short fiber composites is recently growing because of their applications in different industries. The elevated temperature creep behavior of SiC short fibers reinforced A1 alloys is the significant topic of investigations that intended at analyzing the ability of the mentioned composites for using as reinforced materials at the elevated temperature applications [1-10], So, analysis of the crept reinforced materials behavior is significant and fundamental, because, the happening of the creep in the reinforced materials can be risky. So, the plasticity and creep investigation is more important in the various industries. Numerous investigators have analyzed the creep behavior in view of the diverse approaches [1-3].
