T or F: tensile strength and flexural strength testing mean comparing the same thing (strength), the only difference would be the way the force/load is applied.
True
What does strength mean in tensile strength?
The max amount of load (in tension) the material can withstand before breaking or yielding
What can you correlate flexural modulus to?
The material's stiffness
If a part is in tension how is the load applied?
Pulling in opposite directions
What is another name for tensile strength?
Tensile stress
If I described the material as more flexible, would if have a higher or lower flexural modulus?
Lower
Bending load is also called what type of load?
Flexure
What does tensile elongation describe?
Measure of change of size vs the original size (how much did it elongate)
What does modulus describe?
Resistance to deformation under load
What are other types of loads our materials can be under?
Compression, Shear, Torsion
What are some different conditions/variables stress/strain curves can be tested in?
Temperature, moisture (cond. vs DAM)
Which material would have a higher flexural modulus: 21SPF or R513H?
R513H because the glass would increase the material's stiffness/modulus
When in flexure the two sides of the part are experiencing different forces, what are they?
Compressive where the load is being applied, and tension on the opposite side
What does tensile strength at yield describe?
The point at which the material exhibits permanent deformation and is in the plastic region of performance vs the initial elastic region where deformation is not permanent
Why would a material's tensile modulus and flexural modulus be different if they are both describing the material's resistance to deforming?
With an ideal material, they would be the same, but because plastic materials perform differently in compression vs tension the resulting modulus values are different
