Stress relaxation properties of bananas during drying

Journal of Texture Studies, 2021
AbstractBananas' mechanical properties are affected by the ripening and the drying processes since they induce profound microstructural changes. In this study, first, the interacting effect of the ripening and the drying processes on the mode of viscoelastic behavior of bananas was investigated.

RATE OF DRYING AND STRESSES IN THE FIRST PERIOD OF DRYING∗

Drying Technology, 2000
ABSTRACT The paper presents a computer simulated processes and illustrate how the drying induced stresses are influenced by the rate of drying. It is shown that the moisture transport coefficient, and thus the rate of drying, depends on the thermal state of the drying material, defined by the wet-bulb temperature.

Stress Fluctuations in Drying Polymer Dispersions

Langmuir, 2010
Drying polymer dispersions usually experience tensile stress, induced by the reduction in volume and by the rigid substrate. Due to edge-in drying, the stress is usually heterogeneous over the film. Stress peaks play a decisive role in the formation of cracks.

Stress development in drying coatings

Journal of Applied Polymer Science, 2001
AbstractAs a solvent‐cast polymeric coating dries, each part reaches a concentration at which it solidifies and develops elastic modulus. Thereafter, as further solvent departs, that part shrinks out‐of‐plane, but not in‐plane, if the coating adheres to its substrate. Hence, it develops in‐plane elastic stress.

Dry Stress-Induced Phosphorylation ofPhysarumActin

Biochemical and Biophysical Research Communications, 1998
Protein phosphorylation plays important roles in a variety of stress responses. Although plasmodium of Physarum polycephalum rapidly grows and shows an active cytoplasmic streaming under nutrient and wet conditions, dry stress transforms plasmodium into a dormant state called sclerotium.

Drying stresses and strains in a spherical food model

Computers & Chemical Engineering, 2009
An approach to model the drying mechanical effects occurring in a single sphere, representing a food model, is proposed. The mechanical properties were evaluated through compression tests and drying kinetics data were obtained under a laminar fluid flow.

INFLUENCE OF THE DRYING MEDIUM PARAMETERS ON DRYING INDUCED STRESSES

Drying Technology, 2000
A thermomechanical model of drying of capillary-porous materials whose material constants depend on moisture content and temperature is presented in the paper. The finite element method is used for the solution of two-dimensional problem of convective drying of a prismatic bar.

Dilational Lateral Stress in Drying Latex Films

Langmuir, 2010
Drying latex films usually experience tensile stress due to the reduction in volume. While an unconstrained film would shrink affinely in all three dimensions, a coating can only shrink along the vertical and therefore exerts tensile stress onto the substrate.

Apparatus for dry stress corrosion kinetic studies

Review of Scientific Instruments, 1979
An apparatus for carrying out kinetic studies on the dry stress corrosion of threadlike metal specimens in well-determined conditions of uniaxial stress is described. The results obtained by electrical conductivity measurements can easily be related to those obtained by thermogravimetry.

Maps of the stress distributions in drying latex films

Review of Scientific Instruments, 2007
We report on spatially resolved measurements of the mechanical stress in drying polymer films. The technique is based on the deflection of a flexible membrane serving as the substrate. Assuming that the lateral tension of the membrane is the main source of its resistance to deformation, one can show that the local surface stress σf (x,y) is ...
