Abstract:
|
This paper proposes two time-integration algorithms for motion of geometrically
exact 3D beams under sliding contact conditions. The algorithms are derived using the socalled
master–slave approach, in which constraint equations and the related time-integration
of a system of differential and algebraic equations are eliminated by design. Specifically, we
study conservation of energy and momenta when the sliding conditions on beams are imposed
and discuss their algorithmic viability. Situations where the contact jumps to adjacent finite
elements are analysed in detail and the results are tested on two representative numerical
examples. It is concluded that an algorithmic preservation of kinematic constraint conditions
is of utmost importance. |
