Material properties of solid bone elements.

Pelvic parts	Elastic modulus (MPa)				Yield strength (MPa)
	A	B	min	max	C	D	min	max
Ilium [12, 32]	2890	2.63	3.6	12214	32.4	1.85	2	115
Sacrum and lumbar vertebra [33, 34]	4730	1.56	3	11900	37.1	1.74	1	104
Femur [33, 34]	6850	1.49	159	18500	85.5	2.26	2	505
Bone expression [35]

Note. Poisson’s ratio of the bone tissue is 0.3 and postyield modulus is considered equal to 10% of the elastic modulus E [42]. There is a linear relation between bone density () and CT () value, and this formula has been obtained by [35].
