Elastic stiffening in PVA-Borax studied with experimental medium amplitude oscillatory shear
… to measure asymptotically nonlinear viscoelastic material functions across a range of compositions of PVA-Borax with storage moduli ranging from $G_0 \approx 100-3000$~Pa. The material functions can be related to model parameters to gain physical insight into the structure of the material system. …

Complex mechanical design of bio-inspired model transient network hydrogels
The mechanical properties of viscoelastic soft materials are strongly time-dependent, such that we must describe their mechanical properties with material functions. This is an inherently difficult problem for materials scientists: typically,we define structure-property relationships in terms of …

Asymptotically nonliner oscillatory shear: theory, modeling, measurements and applications of nonlinear elasticity to stimuli-responsive composites
Viscoelastic materials, such as crosslinked networks of synthetic and biological polymers, exhibit a nonlinear rheological response to mechanical deformation. Oscillatory shear is a popular deformation protocol for viscoelastic characterization, both linear and nonlinear, the latter referred to as …

Validation of hygrothermal material modelling under consideration of the hysteresis of moisture storage
… is significantly dependent on the applied material functions. These functions are determined by the material modelling marking the connection between the basic storage and transport parameters which are obtained from basic measurements, and the storage and transport coefficients which are …

Integrating novel rheological tools with microscopy to characterize viscoelastic properties of complex materials
Rheological property of any material is the mechanical response when it undergoes stress or deformation. Characterizing these properties is essential because it can help in optimizing the formulation and processing of the materials. Over the years, different rheological techniques have evolved, …

An Investigation of the Rheology of Reactive and Nonreactive Highly Filled Polymer Systems
… measures the dynamic linear viscoelastic material functions of highly filled materials. The relative behavior of the storage and loss moduli with increasing filler content was studied for four different molecular weight materials. The effect of an increase in filler amount on the …

Co-design of surface textures and non-newtonian fluids for decreased friction
… fluids; however, design with more complex materials (for example non-linear viscoelastic materials) can provide ways to enhance performance. The main problems for design with non-linear viscoelastic materials are 1)~there is no universal rheological model, 2)~the non-linear behavior depends …
