Teaching Tool: Finite Element Analysis of 2D Truss Problem by VBA Program
Journal Title: International Journal of the Computer, the Internet and Management - Year 2015, Vol 23, Issue 3
Abstract
Finite element method used for complex 2D truss problem needs computer program to help solving the solutions. The specific engineering programs are licensed and hard to be installed in every computer. But there is EXCEL in every computer. VBA program run on EXCEL was written to solve the 2D truss problem by using basic finite element concept. User inputs information into program: number of nodes, number of elements and their information, boundary conditions, and loads. VBA program automatically calculates information and shows results: stiffness matrix for each element and global stiffness matrix, deformation and reaction solutions, internal forces and normal stresses for each element, comparison picture of problem picture and deformation picture in color shades.
