Composite Plate Bending Analysis With Matlab Code

We discretize the plate domain ( 0 \le x \le a ), ( 0 \le y \le b ) into ( n_x \times n_y ) grid points.

Unlike isotropic materials (like steel or aluminum), composite materials (like Carbon Fiber Reinforced Polymer - CFRP) exhibit anisotropy. This means their stiffness depends on the direction of the fibers. In plate bending analysis, this requires the use of Classical Lamination Theory (CLT).

The code below solves bending of a simply supported rectangular composite plate under uniform pressure. It assembles global stiffness matrix, applies boundary conditions, solves for displacements, and plots deformed shape. Composite Plate Bending Analysis With Matlab Code

The code uses typical Carbon Fiber Reinforced Polymer (CFRP) properties.

Include a complete, runnable MATLAB script or a set of functions. Provide key function headers and brief description. (Below is a minimal, functional Navier-based solver for SSSS plate using CLT and FSDT.) We discretize the plate domain ( 0 \le
