ORTHOTROPIC SANDWICH PLATES

A DYNAMIC RELAXATION SOLUTION IS PRESENTED FOR THE SMALL DEFLECTION BEHAVIOR OF RECTANGULAR ORTHOTROPIC AND ISOTROPIC SANDWICH PLATES OF UNIFORM OR VARYING CROSS SECTION AND SUBJECTED TO ANY SYSTEM OF NORMAL LOADING. THE NECESSARY THEORY FOR THE TREATMENT OF ANY ADDITIONAL IN-PLANE LOADING IS ALSO INCLUDED. ANY COMBINATION OF SIMPLY SUPPORTED FIXED OR FREE EDGES MAY BE SPECIFIED AND ADVANTAGE MAY BE TAKEN OF SYMMETRY ABOUT EITHER OR BOTH CENTER LINES WHEN IT EXISTS. THE ACCURACY OF THE METHOD HAS BEEN VERIFIED BY COMPARISON WITH EXISTING SOLUTIONS. THE DYNAMIC RELAXATION COMPUTER PROGRAM IS USED TO OBTAIN THE SOLUTIONS FOR A NUMBER OF NORMALLY LOADED PLATES, BOTH ORTHOTROPIC AND ISOTROPIC, FOR WHICH SOLUTIONS BY OTHER METHODS ARE ALREADY AVAILABLE. THE PRESENT SOLUTIONS HAVE BEEN SHOWN TO BE IN EXCELLENT AGREEMENT WITH THE EXISTING ONES. THE APPLICATION OF THE SANDWICH PLATE ANALOGY TO THE SOLUTION OF CERTAIN OTHER PLATES OR PLATE-LIKE STRUCTURES UNDERGOING APPRECIABLE VERTICAL SHEARING DEFORMATIONS, VIZ. HOMOGENEOUS THICK PLATES AND MULTICELL AND VOIDED BRIDGE DECKS, IS THE DISCUSSED. /AUTHOR/
