The various tensile properties, such as yield strength, tensile strength, strength coefficient, uniform elongation, strain hardening exponent and strain rate sensitivities, of stainless steel-clad aluminium sandwich sheet metals have been analysed on the basis of the fact that the flow stresses of the sandwich sheets follow the rule of mixtures, an average of component properties weighted by the volume fractions. The rule of mixtures can be applied to the tensile strengths and strength coefficients of the sandwich sheets, whereas the yield strengths do not follow the mixture rule. The force weighted average rule, an average of component properties weighted by volume fractions and forces, can be applied to uniform elongations, strain hardening exponents and strain rate sensitivities of the sandwich sheets. |
