“…The obtained material characterization and model fitting is in perfect agreement with similar studies in the literature 57 – 60 that analogously recognized the 2-parameter hyperelastic Ogden model as the most appropriate and computationally handy model for generalized theories of rubber-like materials.…”

This paper describes the computationally informed design and experimental validation of a microfluidic chip device with multi-axial stretching capabilities. The device, based on PDMS soft-lithography, consisted of a thin porous membrane, mounted between two fluidic compartments, and tensioned via a set of vacuum-driven actuators. A finite element analysis solver implementing a set of different nonlinear elastic and hyperelastic material models was used to drive the design and optimization of chip geometry and to investigate the resulting deformation patterns under multi-axial loading. Computational results were cross-validated by experimental testing of prototypal devices featuring the in silico optimized geometry. The proposed methodology represents a suite of computationally handy simulation tools that might find application in the design and in silico mechanical characterization of a wide range of stretchable microfluidic devices.

“…The established models have been thoroughly reviewed and evaluated by Boyce and Arruda (2000) [1], Steinmann, Hossain, and Possart (2012) [2], and Hossain and Steinmann (2013) [3]. Current multiscale approaches for modeling rubber-like materials and soft tissues have been briefly reviewed and compared with classical macroscopic phenomenological models by Puglisi and Saccomandi (2016) [4].…”

The partial differential equation for isotropic hyperelastic constitutive models has been postulated and derived from the balance between stored energy and stress work done. The partial differential equation as a function of three invariants has then been solved by Lie group methods. With geometric meanings of deformations, the general solution boils down to a particular threeterm solution. The particular solution has been applied for several isotropic hyperelastic materials. For incompressible materials, vulcanized rubber containing 8% sulfur and Entec Enflex S4035A thermoplastic elastomer, three coefficients have been determined from uniaxial tension data and applied to predict the pure shear and equibiaxial tension modes. For a slightly compressible rubber material, the coefficients have also been extracted from the confined volumetric test data.

“…The solutions of the canonical boundary value problems obtained by Rivlin form the basis of many of the developments of the theory (e.g. [3]). Today, many branches of physics and engineering science use the theory of nonlinear elasticity initiated by Rivlin.…”
