Calculation for Uniform Loads
Calculate the estimated thickness of ACRYLITE® acrylic required to support a uniform pressure load over a rectangular flat plate. The calculator assumes simply four-sided supported edges and small deflections.
- Sheet is simply supported on all four edges.
- Load is uniformly distributed over entire sheet.
- Dimensions are open area; do not include supported areas.
- Max allowable continuous stress < tensile strength to prevent stress crazing and creep failure.
- Results most accurate for deflections less than half of the sheet thickness. Request the Extended Calculator at the bottom of this page for additional Technical References.
