- Mapdl.edshell(wpan='', shnu='', shtc='', wpbt='', shpl='', itrst='', **kwargs)¶
Specifies shell computation controls for an explicit dynamics analysis.
APDL Command: EDSHELL
Maximum shell element warpage angle in degrees. Defaults to 20.
Hughes-Liu shell normal update option:
- -2 - Unique nodal fibers. This option is required for SHELL163 (KEYOPT(1) = 1, 6, or
if the real constant NLOC = 1 or -1.
-1 - Compute normals each cycle (default). This option is recommended.
1 - Compute on restarts.
n - Compute every nth substep.
Shell thickness change option:
0 - No change.
- 1 - Membrane straining causes thickness change. Important in sheet metal forming
Warping stiffness option for Belytschko-Tsay shells:
1 - Belytschko-Wong-Chiang warping stiffness added. This option is recommended.
2 - Belytschko-Tsay warping stiffness (default).
Shell plasticity option. This option is only valid for these material models: strain rate independent plastic kinematic, strain rate dependent plasticity, power law plasticity, and piecewise linear plasticity.
1 - Iterative plasticity with 3 secant iterations (default).
2 - Full iterative plasticity.
- 3 - Radial return noniterative plasticity. (Use this option with caution; it may
lead to inaccurate results.)
Triangular shell sorting option. If sorting is on, degenerate quadrilateral shell elements are treated as triangular shells.
1 - Full sorting (default).
2 - No sorting.
This command is also valid in PREP7.
