MECH3300 Finite Element Methods

Concepts. Node - a generalised joint - connection point at which equations are written - there are at most 6 unknowns (degrees of freedom) at a node (3 displacements, 3 rotations)Element - connection between a group of nodes representing stiffness or other properties approximately- interpolation of displacement between the nodal values is used - this becomes more accurate as element size is reducedReference node - an extra point used to orient the cross-section of a beam.
