The understanding of the mechanical properties of bone tissue is essential for the creation of biomechanically compatible artificial materials for human and animal bone defect repair and reconstruction. About 20% of human bone mass is porous tissue known as spongy, cancellous, or trabecular. It forms most of the structures of the epiphyses of long bones, irregular and flat bones, it is the connective tissue with low density, a large surface area, lower mechanical strength than compact bone tissue and it does not contain osteons. Space between trabecular struts in the long bones is filled with vascular red or fatty yellow bone marrow. The bones are subjected to recurrent loadings, but particularities of mechanical characteristics of trabecular tissue in this loading mode are insuficiently explored.
