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.

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.

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.

Stress Effects in Drying Polymer Films

MRS Proceedings, 1994
AbstractA model is developed to predict the magnitude and pattern of stress due to drying of polymer films. This model combines diffusion-and-convection equation with large deformation elasto-viscoplasticity, utilizing concentration dependent elastic and viscoplastic material properties to better represent the behavior of drying thin films.The results ...

Stress development during supercritical drying

Journal of Non-Crystalline Solids, 1992
Although supercritical drying eliminates the capillary stresses that cause damage during conventional drying, there are other sources of stress and strain that can destroy aerogels. During heating in the autoclave, expansion of the pore liquid causes dilatation of the gel network.

Drying-Induced Stresses in Macaroni Dough

Drying Technology, 2006
The mechanical effects like shrinkage and drying induced stresses arising during convective drying of macaroni dough are analyzed in this article. The aim of these studies is to test the sensitivity of macaroni dough on fracture formation caused by shrinkage during drying.

Shades of Dry — Curing Urinary Stress Incontinence

New England Journal of Medicine, 2007
Urinary incontinence is a common condition affecting 20 to 40% of older women.1 The two most common types of urinary incontinence are stress incontinence, the involuntary loss of urine resulting from increased abdominal pressures (such as with a cough or Valsalva's maneuver), and urge incontinence, the involuntary loss of urine after an unwanted ...

Drying of Granular Ceramic Films: II, Drying Stress and Saturation Uniformity

Journal of the American Ceramic Society, 1993
Films composed of ceramic particles were observed during drying. The films were prepared from 20 vol% aqueous dispersions of α‐alumina and α‐quartz and were free of any organic binder. Conditions for uniform film saturation during drying were established by consideration of a liquid transport model and by direct observation of the ...

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.

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.
