In addition to these two methods, an alternative locking-free formulation, a C0 NURBS element with selectively reduced integration is suggested in this study, making use of the traditional selective reduced integration (SRI) rule designed for Lagrangian elements.
"This has reduced integration and development costs, and has limited the amount of storage we will need in the future".
The fundamental theorem reduced integration to the problem of finding a function with a given derivative; for example, xk + 1/ k + 1) is an integral of xk because its derivative equals xk.
Both elements employ the selectively reduced integration method.
Four-node thin shell elements with reduced integration are therefore used to simulate reinforced concrete slabs.
However, theuse of reduced integration resulted in spurious mechanisms or zero energy modesin some cases.
The containment structure was meshed with S4R (shell element reduced integration four node) elements.
SOLID185 element uses enhanced strain formulation, simplified enhanced strain formulation, or uniform reduced integration.
Reduced integration technique is adopted in order to avoid possible shear locking.
A 2D finite element code was used for this study, using axisymmetric elements with reduced integration.
Four-node bilinear elements with reduced integration are used for both the Au and the polymer film.
