Effect of temperature on changes of tensile stress at constant elongation in certain human soft tissues

Experimental study and constitutive modelling of the passive mechanical properties of the porcine carotid artery and its relation to histological analysis: Implications in animal cardiovascular device trials

“…In addition, the test temperature (25 • C) is another limitation since variations from the physiological temperature may affect the mechanical response of the tissue. However, in contrast to Vilks et al [26] and Kang et al [27], Guinea et al [6] showed that these differences in temperatures do not affect the mechanical response of the tissue. In some works such as [9] media and adventitia are separately modelled (using the same SEF with different parameters) which is not the case in the present contribution.…”

Site specific inelasticity of arterial tissue

“…The tissue was tested at room temperature rather than at 37 1C, although it is unclear if this will affect the tissue properties (Guinea et al, 2005;Kang et al, 1995;Vilks et al, 1975). In this study we assume that the peak stress-strain points of each strain level can be used to estimate the monotonic elastic loading behaviour of the tissue (the load envelope).…”

Assessment and design of sleeves for coronary artery bypass grafting

“…It can be inferred from this that, with decreasing temperature the modulus of elasticity of aortic wall increases. Moreover, this increase of the modulus of elasticity reduces the wall deformability as confirmed also by Vilks et. al.…”

“…a: 38.5kPa; b: 25.6kPa; c: 13.6kPa; d: 9.0kPa; e: 6.0kPa (a rectangular sample which was cut out of the wall and exposed to pre-stress). Adapted fromVilks et. al.…”
