| Abstract | A totally new approach of Lagrangian formulation is
presented for large deformation analysis of continua and
structures by the finite element method. In this approach, the
deformation of a finite element assemblage is measured by
assigning a 'nonphysical' parental element as the reference
configuration corresponding to an element in the real domain. It
is called the 'pseudo Lagrangian formulation (PLF)' in this
study.
In the process, a new set of 'pseudo' stress, strain and constitutive tensors are also defined with reference to this
'pesudo' configuration. This will help maintain the general form
of governing equations without sacrificing their rigorness and
generality.
Applications of PLF to small and finite deformation problems
indicate that PLF not only serves as an alternative but has
certain implementational advantages over the traditional (total
or updated) Lagrangian method. |
