Abstract
A novel mathematical model based on mapping function is presented for determination of exact steady state creep behaviour in short fiber metal matrix composites 6061Al/15%SiC (MMC's) subjected to axial loading. FEM and analytical steady state Creep behaviour of 6061Al/15%SiC (MMC's) composites wasn't coinciding to the previous experi- mental results in Prior researches. In this paper, transformation function is introduced in order to convert previous analytical and FEM results to experimental results correctly. Mapping function method (MFM) is exact approach for transformation of analytical and FEM results to experimental results in MMC's. Also, fiber behaviour is elastic unlike creep behaviour of matrix. In addition mapping transformation function is introduced analytically. Eventually, good agreement is established between the results of new mapping function method (MFM) and previous experimental results for prediction of steady state creep behaviour in short fiber composites (SFC's).
