Cellular or Trabecular Solids

WithStuart R. Stock

The subject of this chapter is cellular solids, that is, materials with significant volume fractions of empty, fluid-filled, or soft-tissue-filled space. The features common to engineered materials such as foams and natural cellular materials such as wood or cancellous bone require similar analyses approaches. MicroCT studies of static cellular structures are covered first, followed by studies of temporally evolving, nonbiological cellular materials. Some of the many microCT results on mineralized tissues such as cancellous (trabecular) bone are surveyed, and scaffolds being developed for cell in-growth, that is, as biomedical implants, are covered briefly.
