Vasculaire (veine and artère)
The vascular system is the network of blood vessels including arteries, veins and capillaries that allow blood flow to and from the heart.
À propos de ce matériau
(En anglais seulement) The vascular system is the network of blood vessels including arteries, veins and capillaries that allow blood flow to and from the heart. The structure of the blood vessel walls is mainly composed of endothelial cells, elastin, collagen and smooth muscle cells. The mechanical properties of the different components of the vascular system are studied to learn about: their structural function in the body, the effects of pathologies in blood vessels mechanics and related clinical issues, development in the structural modelling of blood vessels and research in blood vessels physiology.

Comment fonctionne le modèle "Sinusoid"? +
(En anglais seulement) This feature is used to obtain the Frequency, Amplitude and Offset of a sinusoidal signal. A blue line displays the theoretical sinusoid with the Frequency, Amplitude and Offset obtained (Figure 1). The values of the Frequency, Amplitude and Offset are indicated in the "Results" field. The units vary according to the graph’s axes.
This feature can also be used for sinusoidal stimulus-response analysis. Sinusoidal stimulus shall be selected on the x-axis and the sinusoidal response on the y-axis. The Modulus is the ratio of the response Amplitude over the stimulus Amplitude. The Phase is the phase difference between the response and the stimulus. The Modulus’ is computed as the Modulus*Cos(Phase) and the Modulus” is computed as the Modulus*Sin(Phase). A blue line displays the theoretical sinusoidal stimulus-response with the Frequency, Modulus and Phase obtained (Figure 2). The values of the Modulus and Phase are indicated in the “Results” field. The units vary according to the graph’s axes.
One use for this feature would be to compute material properties by multiplying the Modulus obtained by the appropriate geometric factors. For example, the Young’s Modulus can be obtained during uniaxial compression or tension on cylindrical sample with t/pi*r2 as the geometric factor, t is the thickness and r is the radius of the sample.
