Abstract

IN THIS PAPER, NONLINEAR BEHAVIOR ANALYSIS OF AN ASYMMETRICALLY LAMINATED COMPOSITE BEAM (LCB) ON NONLINEAR FOUNDATION UNDER AXIAL AND IN-PLANE THERMAL LOADING IS CONSIDERED. TO SOLVE THE OBTAINED GOVERNING EQUATION A NOVEL METHOD BASED ON LAPLACE TRANSFORM IS USED. THE RESULTED APPROXIMATE ANALYTICAL SOLUTION ALLOWS US TO PARAMETRIC STUDY OF DIFFERENT PARAMETERS WHICH INFLUENCES ON NONLINEAR BEHAVIOR OF THE SYSTEM. THE NUMERICAL RESULTS ILLUSTRATE THAT PROPOSED TECHNIQUE YIELDS A VERY RAPID CONVERGENCE OF THE SOLUTION SERIES AS WELL AS LOW COMPUTATIONAL EFFORT. THE ACCURACY OF THE PROPOSED METHOD IS VERIFIED BY THOSE AVAILABLE IN LITERATURES.
