kin 232 - g2 tissue response to different types of loading

cancellous bone

spongy/trabecular part of the bone

cortical bone

the compact dense part that makes the outside shell

composite

bones are an example of a ___________ tissue as it has different materials

higher, lower

the cortical part of the bone is expected to have the ________ young modulus and can withstand _______ strain

lower, higher

the trabecular part of the bone is expected to have a ____ young modulus and can withstand ______ strain

anisotropic material

any material that has a different material properties depending on the direction of the applied load

isotropic material

a material that has the same material properties regardless of loading direction

true

a longitudinal force has the greatest young modulus and ultimate stress

t or f

false

a transverse force has the greatest young modulus and ultimate stress

compression force

this force involves pushing down onto the tissue

tension force

this force involves pulling two ends of a bone

true

the ultimate strength of a bone depends on the loading type

t or f

neutral axis

the point where tension and compression is 0

bending forcew

this type of loading causes tension at the top and compression at the bottom

true

in bending, the part being stretched is the area with the most concern

t or f

tension

what loading type causes this bone failure

compression

what loading type causes this bone failure

torsion

what loading type causes this bone failure

bending

what loading type causes this bone failure

combined loading

what loading type causes this bone failure

true

during bending, a bone would fail first at the point where there is tension

t or f

stress risers

small concentrated areas (holes, notches, etc) of stress thats causes CSA to be very small

increase

a decrease in CSA causes the stress to

finite model

breaks bones into elements to be analyzed and see the distribution of stress through the material

false

changes in material does not cause a stress riser

t or f

true

cement can be used to help ease the transition of metal to bone

t or f
