Hi Edwin,

Do you know the pressure when the blood vessel fails?

For example, say the blood vessel fails at pressure, P and at this point the wall thickness is W and the blood vessel diameter is D.

This result gives a "tensile strength" of the blood vessel wall as follows:

((PD)/(2W))

This formula assumes that you are testing the vessel on its own (i.e. there is no material other than the blood vessel that is restraining the internal pressure in the vessel).

Does that help?

The formula to calculate the circumferential tensile strength σc\sigma_cσc​ of a blood vessel is:

σc=P⋅r/t​

where:

• P = internal pressure
• r = inner radius of the vessel
• t = wall thickness

This formula is based on the principle that the tensile strength is a function of the internal pressure, radius, and wall thickness.
