Large deflection analysis of unsymmetrically laminated composite plates: analytical-numerical type approach. (English) Zbl 1348.74218

Summary: Large deflection analysis of laminated composite plates is considered. The Galerkin method along with Newton–Raphson method is applied to large deflection analysis of laminated composite plates with various edge conditions. The von Kármán plate theory is utilized and the governing differential equations are solved by choosing suitable polynomials as trial functions to approximate the plate displacement functions. The solutions are compared to that of Dynamic Relaxation and finite elements. A very close agreement has been observed with these approximating methods. In the solution process, analytical computation has been done wherever it is possible, and analytical-numerical type approach has been made for all problems.
