Twisting The Plate With The Logo
This example demonstrates bilateral
torsion of rectangular plates with holes of complicated shape (the logo
of our site). The geometrical model was created in
SolidWorks and was transformed into a finite element model in ANSYS. Finite-element
model consisted of 4344 elements SHELL163, with the element formulation
of Fast Co-rotation, and reduced integration scheme. Mesh was generated using algorithms for automatic
construction without additional manual corrections.
The deforming load was
attached to the finite element model without the need for additional objects. To do this using the
tools of choice were created nodal components, located on the end
faces of the model. The load in the form of
rotation around the axis in mutually opposite directions has been
applied to these components for the entire simulation.
The solution was carried
out on SMP-system with eight cores. Number of processors was
set by the option NUM_PROC = 8 in the configuration file ANSYS. Switching to
multi-configuration was carried out by EDRUN, SMP, 1. An additional flag "1"
indicates the need for consistency of solution (ie, the difference was
eliminated with the solution in the case of one core). Parallel computation
enabled the best use of hardware and speed up implementation of the solution in a few times.
Processing
the simulation results performed in ANSYS postprocessor. With the tools
MainMenu-PlotCtrls-Animate-Over Results has been implemented animation
deformation process, which allowed the area to provide the critical
values of strain and stress.
Qualitative and quantitative characteristics of the physical and mechanical effects on selected stages of loading were carried out using the built-in tools ANSYS.
