Abstract
This paper presents the analysis of the creep behavior for safe designing the fibrous composite devices. Special 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 creeping matrix is described by an exponential creep law, whilst the fibers behave elastically in general. The major plan of the present research work is prediction of the creep behavior in the fibrous composites for preventing unwanted events, over and above, controlling the creep deformation rate theoretically and numerically. Finally, good compatibilities are seen between finite element method and present theoretical method results. As an important result and finding, in general, the mentioned behaviors are ascending along with soft gradients, and so they are controllable and desired.DOI: http://dx.doi.org/10.5755/j01.mech.24.2.19535

Summary
Creep phenomenon may be hazardous for mechanical and electromechanical composites, connections, networks and devices. The metal matrix composites (MMC’s) are generally employed to design the mechanical systems and devices due to their advantages. 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. The elevated temperature creep behavior of SiC short fibers reinforced Al 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 [1,2,3,4,5,6,7,8,9,10]. Numerous investigators have analyzed the creep behavior in view of the diverse approaches [1,2,3]
