This code serves as a tool for streamlining computations in ME4508, specifically aiding in the setup of matrices used in Finite Element Analysis (FEA). The primary functionality is centered around calculating the truss matrix, a crucial step in structural analysis.
The TrussStructure struct now owns its members, which are instances of the TrussMember struct. The truss matrix calculation is facilitated by the global_stiffness_matrix method, which computes the stiffness matrix for the truss structure based on its owned members and associated parameters.
- A (total_nodes * 2) x (total_nodes * 2) matrix representing the truss stiffness matrix
The main function demonstrates the practical use of the TrussStructure and associated methods. It initializes parameters such as Young's Modulus, cross-sectional area, length, and angle, creates instances of TrussMember, constructs a TrussStructure with owned members, calculates the truss matrix, and then visually presents the matrix with appropriate formatting.
Feel free to modify and integrate this code into your ME4508 projects to simplify the FEA matrix setup process. If you have any questions or suggestions, please reach out.
