SYSTEM AND METHOD FOR PREDICTION OF SNAP-THROUGH BUCKLING OF FORMED STEEL SHEET PANELS |
摘要 |
<p>A simplified tool is provided for simultaneous prediction of dent resistance and snap-through buckling resistance of roof panels including the effect of roof bow placement, curvatures of the roof panel, thickness of the roof, and steel grade. In one embodiment, a method of predicting snap-through buckling resistance of a sheet metal panel to an applied load under localized loading conditions is provided, wherein the sheet panel has certain defined geometries. The method includes the steps of: identifying first and second principal radii of curvature of the panel; identifying a thickness of the panel; identifying the distance of a portion of the panel between structural supports; creating a mathematical function to determine load deflection behavior for snap-through buckling; and determining the likelihood of the panel to display snap-through buckling characteristics under various localized applied loads by inputting the parameters.</p> |
