Which vascular condition can result from defects in elastic fibers?

• Atherosclerosis

• Varicose veins

• Hypertension

• Stenosis

In biaxial tests on planar membranes, which of the following assumptions is made regarding shear?

• Only E11 and E22 are assumed to be nonzero.

• Shear is considered significant in the analysis.

• Shear is accounted for by additional parameters.

• Shear is ignored because it is always zero.

What does Fung’s proposed strain-energy function aim to address?

• It aims to simplify the behavior of hard materials.

• It is potentially useful for nonlinear elastic behavior.

• It is only applicable to isotropic materials.

• It eliminates the need for experimental data.

What modification is required in the general constitutive equation for incompressibility in arterial mechanics?

• No modification is needed

• It must be eliminated

• It must be modified

• It must be simplified

What is the significance of Green strains in arterial mechanics?

• They assess intraocular pressure

• They determine the behavior of arteries

• They measure blood flow

• They evaluate lens flexibility

What is the active component of stress in vascular smooth muscle primarily influenced by?

• Blood viscosity.

• Intracellular calcium concentration.

• Arterial diameter.

• Oxygen levels in the blood.

What is the relationship between residual stress and the predicted transmural stresses in arteries?

• Residual stress has no relevance to transmural stresses.

• Residual stress only affects the outer layer of the artery.

• Including residual stress tends to reduce predicted transmural stresses.

• Ignoring residual stress leads to more accurate predictions.

Which of the following statements about the identification of constitutive relations is accurate?

• All soft tissues can be described by a single constitutive relation.

• Constitutive relations can be derived without any experimental validation.

• There is a general consensus on the best constitutive relations for all soft tissues.

• Experimental data is crucial for identifying the constitutive relation.

At what value does a near-spherical neuroangioplasty balloon become unstable?

• A = 50/~1.2

• A = 60/~1.1

• A = 71/~1.38309

• A = 90/~1.5
