In order to prevent the possible singularity due to the reduced integration scheme, hourglass control stiffness was used in the element stiffness calculation.
Hourglassing can be kept in check by invoking a suitable HG control algorithm that creates internal forces to resist hourglass modes. ▫ Hourglass energy, which ...
Hourglassing can usually be controlled by applying internal forces to resist hourglass modes via one of several HG control algorithms. ▫ Hourglass energy, ...
2013年11月13日 — If you want to stick on to reduced integrated elements, you can choose enhanced hourglass control option in section controls (This option is ...
Hourglass modes are element distortions that have zero strain energy. The 4 node shell element has 12 translational modes, 3 rigid body modes (1, 2, 9), ...
R.I. with hourglass control (works for all element types; choice and design of hourglass stiffness is tricky). • Selective reduced integration (works for all ...
The hourglass coefficient for type 6 HG control will typically range from 0.1 (default) to 1.0. For elastic material, use 1.0. For other materials, the ...
