Determining Chassis Stiffness with MATLAB - MATLAB and Simulink Racing Lounge

Introduces you to an efficient approach to determine the structural properties of a steel tube frame using the direct stiffness method.

Determining the structural properties of a truss or beam framework is part of many introductory mechanics courses for civil mechanical engineers. Apart from analytical schemes or graphical methods such as the Cremona plan, displacements and member forces can be calculated using the direct stiffness method. This technique, which is the basis for all considerations within that episode, is a classic first step  to explore the Finite Element Method (FEM).

Starting from an analogy between a truss framework and a FSAE steel tube frame, Christoph explains the basics of the direct stiffness method using an introductory example of a 3-truss framework. He also introduces you to the MATLAB File Exchange where users have contributed various implementations of the direct stiffness method.
