Thermal-Elasto-Plastic Analysis on Occurrence of Liquid Zinc Induced Cracking in Bridge Girder under Hot-Dip Galvanizing

Some Applications of Neural Networks for Condition Monitoring in Industrial Systems for Hot Dip Zinc Galvanizing

The paper describes the abilities of some particular neural network structures (NNS) to provide condition monitoring in a real industrial system, designated for hot dip zinc galvanizing. Condition assessment of a molten zinc bath furnace, and more specifically analysis and prediction of the technical condition in galvanizing kettle walls are also developed in this paper.

Drying and Cracking Effects in Box-girder Bridge Segment

This paper deals with the effect of drying as a moisture diffusion process in a segment of a typical box-girder bridge. Pore relative humidity distributions throughout the cross sections of the plates of the girder are calculated from the diffusion equation, taking its nonlinearity and aging into account. The effect of creep with aging on the stresses produced by drying shrinkage is taken into ...

Plastic Package Moisture-Induced Cracking

With the older “through-hole” technology packages such as the Dual In-line Package (DIP), soldering to printed circuit boards was accomplished using a wave solder. The DIP leads went through holes in the printed circuit board, where they were exposed to molten solder during the mounting process. The DIP’s body was never subjected directly to the solder melt, because it was protected from the he...
