Bone Biomechanics

Question 1

stress

Answer 1

independent variable
stimulus

Question 2

strain

Answer 2

dependent variable
response

Question 3

elastic region

Answer 3

if stress is removed, material will return to original shape

Question 4

plastic region

Answer 4

if stress is removed, material will be deformed

Question 5

yield point

Answer 5

where curve changes from elastic to plastic region

Question 6

failure point

Answer 6

where material fails in response to stimulus (buckles/breaks)

Question 7

ultimate stress/strain

Answer 7

position of maximal stress/strain
highest stess a material can withstand

Question 8

elastic

Answer 8

ability of a material to return to original after force is applied and removed

Question 9

plastic

Answer 9

propensity of a material to undergo non-reversible damage with applied force

Question 10

stiffness

Answer 10

resistance to deformation due to applied force

Question 11

flexibility

Answer 11

ready deformation with applied force

Question 12

brittle

Answer 12

property of a material to experience little plastic deformation before it fails
breaks easily

Question 13

ductile

Answer 13

property of a material featuring large plastic deformation before it fails

Question 14

strength

Answer 14

amount of force a material can withstand and still recover its original shape

Question 15

toughness

Answer 15

ability of a material to absorb energy prior to failure

Question 16

high toughness

Answer 16

large energy absorption before failure
strong and ductile

Question 17

low toughness

Answer 17

low energy absorption before failure
weak and brittle

Question 18

hardness

Answer 18

ability of a material to resist penetration by a harder body

Question 19

softness

Answer 19

propensity of a material to be easily penetrated by a harder body
