Determining Chassis Stiffness with MATLAB

Christoph Hahn, technical education specialist at MathWorks, introduces you to an efficient approach to determine 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.

suppose u r analysing a complex fabricated structure can they be analyzed on matlab and can we define stiffness of the supports?
most of the software give only options of fixed supports cud u please help us?

Super gemacht, nice in m.file. How to get this stuff in .mdl 's? hearing around SIMULINK is mutch easier to integrate energy into force over all possibilities e.g. angels, speed of forces or environment condition like e-modul of material in your chassis. Have you any recommendations?
Awaiting your regards
Thanks

m not clear how dof =6 when initially it was =4??
