.... Such a need can be suppressed because the material’s tensile and compressive strengths are asymmetric in the case of large deformation. A sample with two symmetric notches is analyzed in this subsection. The geometry and boundary conditions are depicted in Fig. 6( a ) . A small velocity boundary...

... and instability of soft hollow cylinder is analyzed. By incorporating surface energy density function into the constitutive model of a hyper-elastic theory, explicit solutions are obtained for the large deformation of soft hollow cylinder under the uniform pressure loading and geometric everting. The surface...

... [ 41 – 44 ]. Here, we formulate a large deformation theory. We take the dry network as reference state and denote it as B 0 (Fig. 1 ). Each material point is denoted by X in B 0 . After deformation, the material point X moves to a new position with coordinate x in the current configuration...

... primarily downward, until an unstable lateral jump occurs to minimize the energy stored in the elastic medium. Such an instability is unique to soft materials undergoing large deformation. A two-dimensional plane-strain finite element analysis is used to simulate the 3D phenomenon. 1 Corresponding...

... of nonwoven networks has been well established for elastic deformations. However, the mechanical properties of the polymer fibrous networks with large deformation are largely unexplored, while understanding their elastic and plastic mechanical properties at different fiber volume fractions, fiber aspect ratio...

... swelling large deformation surface instability An aggregate of a polymer network and small molecules (e.g., water) forms a polymeric hydrogel. In response to various environmental stimuli (e.g., temperature, vapor pressure, pH, and electric field), a hydrogel can swell or shrink dramatically...
