Effect of axial prestretch on inflation instability in finitely extensible thin-walled tube

Popis výsledku v původním jazyce

Mechanical response of elastic materials undergoing large deformations exhibit several kinds of a loss of stability. Such a situation may occur, for instance, when a thin-walled cylinder is inflated by an internal pressure. The loss of stability is manifested by a non-monotonic relationship between the inflating pressure and the circumferential stretch of the tube. The results, known from the literature, show that hyperelastic materials with so called limiting chain extensibility property always exhibita stable response for sufficiently small values of the limiting extensibility parameter Jm. In other words, rapid large strain stiffening prevents elastomeric materials from an onset of instability. The present study demonstrates how axial prestretch ofthe thin-walled tube affects the stability of the deformation. It is shown that for axial prestretches ?z = 1 (non-prestretched), 1.05, 1.1, 1.2, 1.5, 2, 3, and 5 the stable inflation is obtained for materials with Jm = 19.11, 20.32, 21.
