... fatigue cracks fatigue testing geometry plates (structures) stainless steel temperature distribution It has been recognized that crack initiation and propagation of fatigue and creep-fatigue test at elevated temperature are important to evaluate life prediction. Watanabe and Koike ( 1...

... of this paper is to investigate and understand the temperature distribution during EF welding. A one-dimensional transient heat-transfer model was proposed, taking the variation in the rate of power input, the phase transition of PE, and the thermal contact conductance between heating wire and PE...

... boundary conditions, a generalized series based on a new and infinitely differentiable polynomial was employed to inversely determine the transient temperature distribution in a semi-infinite slab using only a single temperature history. These temperature distributions were in turn used to find...

.... This paper employs the continuous-time analog Hopfield neural network (CHNN) to compute the temperature distribution in various forward heat conduction problems. An efficient technique is then proposed for the solution of inverse heat conduction problems using a three-layered backpropagation neural network...

... ). The direct route addresses failure modes directly, having, therefore, advantages in comparison to the traditional method, which is stress categorization. Special attention is given to the progressive plastic deformation design check (PD-DC) with space and time-dependent temperature distribution...

... the carbon steel from exposure to excessive temperatures. The temperature distribution in the steel tube-sheet–tube-ferrule system is affected by process gas flow and heat transfer through the assembly. Rather than depend on “assumed” heat transfer coefficients and fluid flow distribution, a computational...

... a comparison of the predicted time-averaged temperature distributions by the three models with the experimental data at six vertical locations. It is shown that the V2-f model best predicts the time-averaged temperature distributions. All the models predict similar temperature distributions near the inlet...

.... Knowledge of the thermal history and temperature distributions are thus critical in developing control schemes for acceptable residual stress distributions to improve in-service component behavior. A comprehensive study of three-dimensional temperature distributions in a stainless steel tee branch junction...

... of the temperature distribution as a function of time and radial position was then used to derive new relationships for the transient thermoelastic stress states. The derived expressions allow an easy analysis of the significance of the exponential terms and convective coefficient in determining the magnitudes...
