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
