Dynamic and time-stepping schemes for elastic shells undergoing finite rotations

Brank, Boštjan (avtor), Korelc, Jože (avtor), Ibrahimbegović, Adnan (avtor)

In this work we study the time-stepping schemes for shell models, which describe the shell-director vector motion by the finite rotations. Different possibilities for choosing director rotations are examined and their relationships are cast in terms of the commutative diagram. The Newmark time-stepping schemes, making use of different rotation parameters, are then developed. The mid-point scheme modified to either conserve or dissipate the total energy is further examined. Several numerical simulations are presented to illustrate the performance of each developed scheme.
