Subject
For this calculator, the term ‘sheet’ refers to rectangular plates as opposed to [circular] plates. Unlike [circular] plates, the behaviour of sheets under load is a little more difficult to predict given the multitude of potential edge support configurations.
The general loading conditions for sheets may be either uniform, such as pressure from wind or liquid (which varies with depth), or from a concentrated force at any location within its edges; or a combination of the two.
The edge supports usually associated with rectangular plates or sheets are; fixed, guided, simple or free, which may be applied in any form or configuration.
The user enters a location anywhere on the surface of the sheet where the sheets calculator will determine its performance under load in both ‘x’ and ‘y’ directions, using the strip calculation method.
SHEETS allows the user to apply any combination of the four available support options to any of the four edges, irrespective of the sheet's aspect ratio. Moreover, a different (linearly variable) pressure may be applied to any edge - in either direction.
Whilst the output data at 'x,y', as defined below, is always listed in the Data List window, the user may also include an extensive co-ordinate listing for the strips passing through the ‘x,y’ location to plot in a suitable spreadsheet program.

Combined Stress
There is just one calculation option in SHEETS, but it includes two loadcases - variable pressure and a concentrated force - and four support options in any combination.
