The maximum stresses and center deflection at high pressures differ less than 3 percent from those derived by Boobnov for an infinitely long plate with clamped edges. This agreement suggests that clamped plates with a length-to-width ratio greater than 1.5 may be regarded as infinitely long plates for purposes of design.

Results of tests show that a slowly rising condenser-discharge preheat current with a rapidly rising welding current afford no less expulsion than a rapidly rising welding current alone, and was inferior to a slowly rising welding current alone. In one case using slowly rising current for preheating and welding proved beneficial although generally, utilizing a raised electrode welding force to decrease expulsion was more practicable. Postheating had no effect on sheart strength until the current sufficient to remelt the welds, which greatly increased the weld diameter and shear strength.

This document presents the solution of Von Karman equations for thin plates with large deflections for special cases of rectangular plates of 1.5 and 2.0 length-width ratios under uniform normal pressure. The boundary conditions approximate panels with riveted edges under normal pressure greater than that of the surrounding panels. Center deflections (to twice the plate thickness), membrane stresses, and extreme-fiber bending stresses are given as functions of the pressure. For small deflections, the results are consistent with those given by Timoshenko.

Von Karman's equations for thin plates with large deflections are solved for the special cases of rectangular plates having ratios of length to width of 1.5 and 2 and loaded by uniform normal pressure. The boundary conditions are such as to approximate panels with riveted edges under normal pressure greater than that of the surrounding panels. Center deflections, membrane stresses, and extreme-fiber bending stresses are given as functions of the pressure for center deflections up to twice the thickness of the plate. For small deflections the results are consistent with those given by Timoshenko.
