    Unconstrained motion in hamiltonian mechanics

    Hello everyone, I am currently working on a bar-linkage simulation and decided to use multibody dynamics to try to perform this analysis. So basically everything seems simple and clear for examples such as double-pendulums or 4-bar linkages. And i obtain the lagrangian equations or hamiltonian...

    Rigid-body only FEM

    Hi everyone, I am currently trying to program a MATLAB FEA code that would only take into account large rigid body deformations (no strains, no stress, I might implement this later) for bar linkages (will also head toward beams and more complicated elements later) and the trouble I have is...
