Chp 4 Hooke's Law: Elasticity of Tissues and Compliant Vessels Flashcards
1
Q
Define Tensile Stress
A
forces that pull apart a sample or push it together.
σ = F/A
2
Q
Define Strain
A
E = (l - l0) / l0
3
Q
What is Hooke’s Law formula?
A
σ = E ɛ
4
Q
What is Elastic Modulus?
A
E, aka Young’s Modulus or stiffness. The slope of stress-strain plot.
5
Q
Define Ultimate Stress
A
Eventually all materials will fail by fracturing. This stress point is known as ultimate stress.
