| Abstract | ||||
| Nowadays, it is well known that Aluminum and its alloys, when reinforced with different particulate materials, can provide designers with a group of composites of some valuable mechanical properties such as elastic modulus, poi$son'<ratio, ultimate strength, ductility, internal friction, and wear characterization. Such mechanical properties are important aspects in the design procedure for many moving and rotating parts ie the mechanicalfield. Fiding them through an experimental way is a hard and long way as the designer needs to prepare~many,composites al1oys:with different contents in order to find the best fit for his,'desig". . .. I Finding imperical formulae, which describe these mechanical properties, gives the chance to choose the contents of the composites materials very near to the desired contents and hence reducing the nuhber of specimens needed in the experimental work. In the present work, the authors suggesting some imperical formulae based on statistical approach for thk ixpeiimental results oh the composite material AL-7Wt% SiIAI,Op As &example, the.wear-: rite can be predicted on different .! i..ii. loads and fbr'many sliding distiirices as bell:!
