本文给出了与多孔超弹性区域膨胀有关的径向和球对称问题。孔隙超弹性理论是一个方便的框架，用于模拟高度变形材料的力学行为，其中孔隙空间充满流体。包括耦合的超弹性多孔骨架和流体的机械响应被认为是一个重要的考虑应用的结果，特别是在生物力学应用中遇到的软组织。径向和球对称问题的解析解涉及环形域的基准的标准计算方法的准确性。本文还产生适用于超弹性的解决方案时，耦合是通过一个高渗透性的孔隙结构的存在下消除的结果。
The paper presents the radially and spherically symmetric problems associated with the inflation of poro-hyperelastic regions. The theory of poro-hyperelasticity is a convenient framework for modelling the mechanical behaviour of highly deformable materials in which the pore space is saturated with fluids. Including the coupled mechanical responses of both the hyperelastic porous skeleton and the fluid is regarded as an important consideration for the application of the results, particularly to soft tissues encountered in biomechanical applications. The analytical solutions for radially and spherically symmetric problems involving annular domains are used to benchmark the accuracy of a standard computational approach. The paper also generates results applicable to the hyperelastic solutions when coupling is eliminated through the presence of a highly permeable pore structure.
