Stress-Strain Curves
Linear portion of the curve
What is ELASTIC or Young's MODULUS
This mechanical test involves pulling on the material in opposite directions
What is a TENSILE test
This type of deformation results in permanent deformation since bonds break and reform
21 Pilots song that requires knowledge of the cross-sectional area.
What is STRESSED OUT
This class of material may have yield stress nearly the same as tensile stress
What is a CERAMIC
Area under the curve
What is TOUGHNESS
This mechanical test involves applying forces on an object towards each other
What is a COMPRESSION test
This type of deformation stretches the bonds; when the force is released, the bonds return to their original position
What is ELASTIC
Shakira says these don't lie, but they need to be tough and stiff
What are HIPS
CFRC
What is a Carbon Fiber Reinforced Composite.
Highest point of the stress-strain curve
What is the Ultimate Tensile Strength
This test is pretty twisted; one example of its use is on titanium screws in orthodontics
What is TORSION
Force and displacement in a spring are equated according to this proportionality constant
What is a SPRING CONSTANT
This achy breaky organ won't break if the valves remains tough with a low modulus of elasticity
What is the HEART
Generally, this class of materials is the least stiff.
What are POLYMERS
Length of material at failure
What is ELONGATION at BREAK
A submarine should have this mechanical test conducted.
What is a HYDROSTATIC pressure test
Degree of plastic deformation at failure
Taylor Swift was really singing about the portions of a test specimen at the end of its TENSILE test.
What is WE ARE NEVER GETTING BACK TOGETHER AGAIN.
This type of atomic packing of this class of materials leads to the largest number of slip systems and therefore are the most DUCTILE.
What are FCC METALS
Stress which causes onset of permanent deformation
What is YIELD STRESS/STRENGTH
Often used to test the bending strength of brittle materials
Plastic deformation in crystalline materials results from shear of crystals along this feature
What is a SLIP PLANE
"Every rose has its thorn." This Band is missing an "s" from its name for this mechanical characteristic.
What is POISSON's ratio?
Of the composites, this type is generally the lowest in density.
What is WOOD
