To model a finite element beam in bending using MATLAB, it's recommended to develop a custom solution rather than relying on built-in algorithms, as no specific MATLAB function exists for this purpose. While there are public programs that utilize MATLAB for finite element analysis (FEA), they may require significant time investment to learn, potentially detracting from the understanding of FEA fundamentals. A suggested approach includes meshing the beam in dedicated finite element software, exporting the connectivity and nodes matrices to a text file, and then importing and modifying these files in MATLAB for analysis. Further details or specific questions can help refine the guidance provided.
