Abstract In this talk, we present some analytical results concerning localized instabilities in stretched soft cylinders
with residual-stress effect. Within the framework of finite elasticity, a bifurcation analysis is carried out
based on the incremental theory. It is found that with the residual stress effect taken into consideration
additional singularities of the incremental equations appear. To overcome this difficulty we apply the Stroh
formulism and an expansion methodology and derive a bifurcation condition. Then we consider three
loading scenarios and perform a detailed analysis of the bifurcation behaviors. It turns out that the zero
mode, giving rise to localization, is always… More >
