Soft polymeric materials such as elastomers and hydrogels have played a significant role in
recent interdisciplinary research. They are subjected to large stretch and high cyclic loading …

The synthesis of precisely controlled polymer networks has been a long-cherished dream of
polymer scientists. Traditional random cross-linking strategies often lead to uncontrolled …

Many classic hyperelastic models fail to predict the stress responses of soft materials in
complex loading conditions with parameters calibrated through one simple test. To address …

The elastic moduli of elastomeric materials are predicted by the affine or phantom or junction
affine network models. Although these models are often used, we do not know the …

It is a long-standing challenge to predict the general constitutive behaviors of soft elastomers
under finite deformation, since most of the constitutive relations calibrated from uniaxial …

Mechanical behaviors of a polymer gel are coupled with its swelling behavior. It has been
known that typical hydrogels display extension-induced swelling and drying-induced …

The structure and mechanical properties of model polymer networks consisting of alternating
tetra-functional poly (ethylene glycol) s (PEGs) and bis-functional linear PEGs were …

The three-dimensional structures of polymer networks are formed through two types of
crosslinks: static and dynamic. Although the characteristics of crosslinks strongly influence …

The realization of an ideal polymer network that is free from heterogeneity is one of the
ultimate goals in polymer science. Heterogeneity is known to be an inherent property of …

The cyclic stretching measurements in various geometries including uniaxial, planar,
unequal, and equal biaxial extension reveal the distinctive features of the internal fracture in …
