Aortic Wall as a ‘Two-phase’ Material

Naturevolume 199pages606608 (1963) | Download Citation



COMPARISON of the orientation of the collagen and elastin components of the rabbit aorta at various distending pressures indicates that the media functions as a ‘two-phase’ material. At physiological pressures, collagen fibres of high tensile strength and relatively high modulus of elasticity bear most of the stressing force; an intricate network of elastin lamellae and fibrils of relatively low modulus of elasticity distributes stressing forces uniformly.
