Effect of temperature gradients on cure and stress gradients in thick thermoset castings

Journal of Applied Polymer Science, 1980
AbstractThe temperature gradient developed during casting of an unsaturated polyester for which the kinetics of reaction and the heat capacities, thermal conductivities, and densities were known from earlier work was measured experimentally as a function of time in a thick casting and compared with predicted values calculated from a mathematical model.

Effect of size and stress gradient on fatigue behaviour

International Journal of Pressure Vessels and Piping, 1994
Abstract The effect of specimen size and stress gradient on fatigue behaviour is presented. The analysis was performed on smooth specimens and on edge-notched plates of an aluminium alloy, using both analytical and numerical methods. The specimens were assumed to have through-thickness surface cracks and were subjected to bending and axial loads ...

Effective Widths of Unstiffened Elements with Stress Gradient

Journal of Structural Engineering, 2004
Current American design provisions treat unstiffened elements under stress gradients as if they were uniformly compressed for effective width calculations. Australian, British, and European design provisions allow accurate calculation of the elastic buckling coefficient, however, the same effective width equation for compressed elements is used for ...

Size effects, stress and couple stress gradients in jointed rock

Mining Science and Technology, 1990
Abstract Similarities exist in fracture processes between microfaults and megafaults. Yet, there are size effects when predicting deformational and strength characteristics of jointed rock masses from sample tests. Stress concentrations, forming stress gradients, are different to couple stress gradients derived from couple moments.

Effect of growth temperature gradients on residual stresses in halides

Materials Research Bulletin, 1975
Abstract Thermal gradients experienced by alkali halide crystals during growth by the Czochralski process were measured. The optical homogeneity of the crystals was measured interferometrically. Refractive index variations are shown to result from the temperature gradients during growth which produce thermoelastic strains that are quenched and result

The effects of stress and temperature gradients on fatigue life

Engineering Fracture Mechanics, 1994
Abstract A method is developed that establishes a lower bound on fatigue life due to non-uniform multiaxial stress (strain) and temperature distributions. The method allows prediction of fatigue crack initiation at notches, where stress (strain) gradients are always present, from isothermal uniaxial fatigue tests.

Bounds for the Effective Stress of Classical and Strain Gradient Plastic Composites

SIAM Journal on Applied Mathematics, 2009
Given an average strain, rigorous bounds are established for the stress in a deformation of a plastic composite material, which follows a power law. The deformation theory of strain gradient plasticity, which introduces an internal material length scale, is used. It falls into the classical deformation theory of elasto-plasticity when this length scale
