摘要:
Properties of common engineering materials should be considered in the light of particular requirements. One such requirement occurs in design for minimum weight when materials can be more properly assessed on the basis of a figure of merit which involves the density as well as the normal mechanical properties. It is shown that, for compression members, the structure efficiency varies as the inverse square of the density so that greater benefits may be obtained by decreasing density than by increasing the strength or stiffness. Some applications are briefly considered.
