Zusammenfassung
Of interest here are the class of static/dynamic finite deformation
problems that arise in computational mechanics, and the question
of the suitability in employing the total strain measure for this
class of problems is raised. An attempt to resolve the problem by
proposing a new arbitrary reference configuration (ARC) framework
is described in this exposition. The ARC framework consists of the
ARC elasticity, which bridges the Truesdell stress rate hypo-elasticity
and the St. Venant-Kirchhoff hyperelasticity, and the ARC Lagrangian
formulation, which bridges the updated Lagrangian formulation and
the total Lagrangian formulation. The ARC framework serves as a generalized
computational framework to handle both the computational infinitesimal
and the finite deformation/strain deformation applications in a consistent
and unified manner. In part II of the paper 1, we further extend
the ARC framework to elasto-plasticity.
