A Systematic Study of GelMA‐Carbopol Bioinks for High‐Fidelity Extrusion 3D Bioprinting at Physiological Temperatures

Advanced Healthcare Materials, EarlyView.
Gonzalez Martinez and collaborators develop a strategy to formulate high performance GelMA‐based bioinks with low solids contents. The resulting bioinks enable 3D bioprinting at 37 °C of high‐fidelity structures with tunable mechanical properties that support high cell viability and function.

Plane stress analysis of FRP laminated composites based on homogenization considering the viscoelastic behavior of the resin

Nihon Kikai Gakkai ronbunshu
To efficiently evaluate the anisotropic viscoelastic behavior of thin laminated composite plates, a theoretical framework is developed by reducing a three dimensional anisotropic viscoelastic constitutive law to plane stress conditions and integrating it

Changes in viscoelastic properties of articular cartilage in early stage of osteoarthritis, as determined by optical coherence tomography-based strain rate tomography

BMC Musculoskeletal Disorders, 2019
Background Biomechanical changes in articular cartilage are associated with the onset of osteoarthritis. We developed an optical coherence tomography-based strain rate tomography method: stress relaxation optical coherence straingraphy (SR-OCSA).

Viscoelastic stress relaxation in human skeletal muscle

Medicine & Science in Sports & Exercise, 1992
Viscoelastic stress relaxation refers to the decrease in tensile stress over time that occurs when a body under tensile stress is held at a fixed length. The purpose of this study was to demonstrate viscoelastic stress relaxation in human skeletal muscle.

Finite Element Analysis for Linear Viscoelastic Materials Considering Time-Dependent Poisson’s Ratio: Variable Stiffness Method

Applied Sciences
For linear viscoelastic materials, this paper proposes a finite element analysis method based on an integral constitutive relationship that can simultaneously consider the relaxation behavior of the elastic modulus and the creep Poisson’s ratio. Firstly,

Linear viscoelasticity of gluten: Decoupling of relaxation mechanisms [PDF]

Journal of Cereal Science, 2017
The influence of water content on the relaxation dynamics of mesoporous gluten networks has been explored in a wide range of temperatures. The systems were investigated in the linear viscoelastic region by means of stress relaxation, creep and numerical analysis of data.

Relaxation Constant in the Folding of Thin Viscoelastic Sheets [PDF]

Physical Review Applied, 2020
If one folds a thin viscoelastic sheet under an applied force, a line of plastic deformation is formed which shapes the sheet into an angle. We determine the parameters that define this angle experimentally and show that, no matter how much load one applies, it is impossible to make angles less than a certain minimum angle in a definite time. Moreover,
