2D FEA
To determine the stability and durability of a given structure under various
loading situations, you need to observe the stress and deformation in the
components while they are being loaded. A structure is considered to be
durable if the maximum stress is less than what the material permits.
There are various computational methods for calculating deformation and
stress conditions. One of these methods is called the Finite Element Analysis.
The knowledge gained from this stress rating may lead to changing the
structure in certain areas, which in turn necessitates changes to the design.
The FEA routine uses its own layer group for input and output.
Note that FEA is not designed for solving all special FEA tasks. Its purpose is
to provide you with a quick idea of the stress and deformation distributions.
NOTE The ISO standard parts have to be installed for this tutorial exercise.
For this exercise, work with mechanical structure disabled.
