The mechanical properties of cellular solids
SpletA number of studies have indicated that imperfections in cellular solids can have a very large influence on their mechanical behavior. Waviness in cell walls can drastically reduce elastic stiffnesses, and various irregularities can reduce the effective strengths by … SpletThe first is exceptionally stiff and strong for a given mass; the second is compliant and, although not strong, it absorbs energy well when compressed. This paper summarizes a little of the way in which the mechanical properties of cellular solids are analysed and illustrates the range of properties offered by alternative configurations.
