Implication

Quasi energy and momentum conservation implemented in quadrilateral shells demonstrates improved accuracy in large deformations, suggesting potential applications in multi-body dynamics.

Key Points

The proposed algorithm ensures conservation of energy and momenta in elastic shells, yielding results with high reliability and accuracy.
When subjected to impulse loads, the shells show excellent agreement with existing solutions, validating the method's effectiveness.
System dynamic equations are derived using Hamilton's principle, integrating vectorial rotational variables for enhanced flexibility.
The Newmark scheme transforms these equations into nonlinear forms, facilitating the analysis of large deformations in multi-body dynamics.
