Finite Element Analysis, Part I

Uploaded by bhadeshia123 on Apr 23, 2011
In finite element stress analysis, the elastic body is first divided into
discrete connected parts, which are the "finite elements". The points
at which the elements are connected are the "nodes. The process of
dividing the domain into elements is called "discretisation" and the
pattern of elements is the "mesh". We then relate, using a "stiffness matrix", the forces applied to the nodes of a single element and the
resultant nodal displacements. The final step is to combine together all
the stiffness matrices of the individual elements into a single large matrix
which is the "global stiffness matrix". We shall now illustrate this
process using linear elastic springs.
