Role of High Order Functions in Analysis of the Creep Behavior of a Short Fiber Composite 'Silicon Carbide/Aluminum 6061'

A new analytical approach is proposed to analyze the steady state creep in a short fiber composite SiC/Al6061 (Silicon Carbide/Aluminum 6061) under axial load based on high order displacement functions. The creep behavior of the matrix is described by an exponential law, while the fibers behave elastically. The main originality and purpose of the present paper is to predict the creep behavior in the short fiber composite “Silicon Carbide/Aluminum 6061 using high order functions analytically. The paper is presented in order to prevent undesirable events, as well as controlling the creep deformation rate. Good agreements are found among available experimental methods, FEM and present analytical approach results. As a result, most behaviors have ascending behaviors with smooth gradients, and also are controllable.
