A model of describing creep strains and porosity evolution for a hollow cylinder affected by internal gas pressure
Two plane-strain states of two identical hollow cylinders are considered, where one is made of a material with porosity evolution and the other is made of an incompressible material. For each hollow cylinder, the process of inflation begins from an undeformed state and ends as soon as the external boundary radius reaches a certain set value. In the assumption that the porosity increases and reaches its highest value at the outer boundary radius, the two hollow cylinders are compared in terms of their strains and stresses.
