摘      要：With slidable cross-links along the polymer strands,topological gels can adjust their network topology in response to the imposed *** reported in experimental studies from the literature,the unique cross-linking strategy and the distinct deformation mechanism result in a peculiar multiaxial behavior with minimal strain-coupling between different principal directions at relatively low cross-linking *** paper presents an element-free modelling of the topological gels focusing on their nonlinear stress–strain behavior under general biaxial ***,conditions of uniaxial stretching and the three types of biaxial deformation,i.e.,equibiaxial stretching,pure shear deformation,and“two-stepbiaxial deformation are *** numerical stress–strain curves for these conditions are compared against those from the literature.
