In a loaded lamina of complicated shape stress concentrations arise which it is difficult to calculate. A model in the form of an electrolytic tank may be used to find the resultant stress at any point in a loaded lamina. The tank is made of an insulating material in the same shape as the lamina and filled with an electrolyte. It is fitted with electrodes to represent the areas over which the load is applied. The loads are represented in magnitude by the alternating currents flowing through the electrodes and in direction by the relative phase angles of the currents. The electric current at any point in the model tank can be sampled with a probe consisting of two fine wires a short distance apart. The resultant stress at a point in the loaded lamina is proportional to the electric current at the corresponding point in the model tank. This approach offers a valuable addition to means already available for finding stress concentrations in laminae of complicated shape.
