Metals, Alloys and Corrosion
Galvanic Corrosion Potential Chart by Penn Manufacturing and manufacturing Corp.
Galvanic corrosion potential is a measure of how dissimilar metals will corrode when placed against each other in an assembly. Metals close to one another on the chart generally do not have a strong effect on one another, but the farther apart any two metals are separated, the stronger the corroding effect on the one higher in the list.

Note: This is in PDF format. Acrobat reader is required.

Summary

The origin of non-linear creep in plastics is explained and illustrated with data for a grade of PVC (polyvinyl chloride). Some simple mathematical functions are presented that give an approximate model of the creep behaviour.
Non-linear creep of rigid materials is analysed in finite element systems using models based on time-dependent plasticity. This article shows how these plasticity equations can be interpreted to represent the functions derived to model creep in plastics.
Derived materials parameters are then used in a finite element analysis of the creep of a simple PVC component to illustrate stress redistribution in the component resulting from the description of the non-linear behaviour.
