A calculation of average stress in electrodeposits based on the bending of a flat-plate substrate

Hitherto the classical formulae for calculation of the average stress in electrodeposits on the basis of the measured deflections of a strip bent as a result of one-sided plating have been widely used. A study of these formulae reveals that they do not show sufficient accuracy to satisfy all the equations of the mechanics. In view of this, a new theoretical model of the force interaction between the deposit and the substrate is proposed in this work and a new formula for calculating the average stress has been derived. The model conforms to the generally accepted simplifying assumptions made by other authors concerning the stress in electrodeposits, while at the same time accurately satisfying all the basic equations of the theory of thin elastic plates.
