C3D8
Linear Cube/Brick
Number of Nodes: 8
Number of DoFs: 3 (All Translation)
Supports Body Force
Constant Consistent Mass Matrix With Same Order Integration
Syntax
Remarks
Three integration schemes are available, they are:
"I" uses Irons six-point scheme.
"R" uses reduced integration with Gauss scheme, that is one point at the center of the element. Hourglassing control is automatically enabled.
"G" uses full integration (2nd order) with Gauss scheme.
The nonlinearity is implemented by using total Lagrangian (TL) formulation, turn on the switch to use it.
In the above, is identical to Eq. (47) in the reference paper. Thus, shall be set to some value proportional to the elastic modulus.
