Material Science Quiz 3 Review |UPDATED!!
Que & Answ
1. Elastic deformation: recoverable deformation
2. Plastic deformation: permanent deformation
3. Standard cylindrical (left) and flat (right) specimens used in ten- sile testing:
dog-bone
4. Hooke's Law: ÃE=µ
5. Strain is in the linear elastic range.: recoverable
6. Linear-elastic range:: Linear means Ãa n d µare related in a linear fashion
7. E: stiffness of a material
8. Yield point:: The point on the curve when the elastic range ends.
9. occurs at the onset of plastic/permanent deformation: Yielding
10.After the yield point, any additional deformation is not recoverable and is
.: permanent
11.Brittle materials don't exhibit .: yield point
12.Ultimate tensile strength is the on the s-e curve.: peak point
13.The ultimate tensile strength has the largest stress otherwise known as
.: necking
14.Fracture point:: The point on the curve where the specimen fails.
15. is the property of a material enabling it to undergo considerable plastic deformation under
tensile load before fracture.: Ductility
16.As a specimen is elongated under a tensile load, its diam- eter must
decrease.: elastically
17.Poisson's ratio is always positive in materials and ranges from
0.25 to 0.4.: isotropic
18.A measure of the amount of energy needed to cause yield in the material.-
: modulus of resilience, Ur
19.The is the amount of energy required to fracture the material (or the ability of
materials to absorb energy before fracture) .: modulus of toughness
20.The modulus of toughness is a measure of combination of and
.: strength, ductility
21. and are determined based on instantaneous cross-sectional area
and length of the specimen.: true stress, true strain
22.True stress is always than engineering stress.: grater
23.Metal Forming Operations :: Metal ingots are formed into functional shapes using a variety of operations such
as: casting, forging, rolling, stamping, drawing, and extrusion.
