Main mechanical properties reported in literature for vascular substitutes (colored circles), the corresponding mechanical testing methods in which they can be obtained (black rectangles), and the main variable parameters of their protocols (blue rectangle). In each blue rectangle (right), two or more options are available as detailed in section 3. EB, elongation at break; SB, strength at break; YM, Young elastic modulus; IEM, initial elastic modulus; EEM, equilibrium elastic modulus; CP, creep profile; E′, storage modulus; E′′, loss modulus; BP, burst pressure; C, compliance.
