Total hourglass control for hyperelastic materials Original Research Article

Incremental hourglass control formulations lead to erroneous results when problems associated with large and complicated deformations are considered. This fact is shown analytically by way of a simple example. Accordingly, a novel hourglass control method based on the total Lagrangian formulation is presented which avoids the detected problems. The formulation is physically based and no empirical factor has to be estimated. A closed form thereby has been developed for explicit finite element codes and 3D-hexahedral elements.
