Calculating Stress Using
FEA

In this tutorial, you calculate the stresses in a lever using the finite element analysis (FEA) in
AutoCAD

Mechanical. You use the results to improve the design of the lever.

Key Terms

Definition

Term

A load or force that is exerted over a certain length.

distributed load

Finite Element Analysis. A calculation routine based on analyzing a
rigid body subject to loads and restraints for stress, strain, and defor-
mation.

FEA

A support that prevents translation as well as rotation about all axes.

fixed support

Force or moment acting on a member or body.

load

A support that prevents rotation in all axes, but allows translation
along one axis.

movable support

A single edit command for the objects in your drawing.

Power Edit

The force acting on a member or body per unit area.
