Example Cantilever beam

E = 210000N/mm2

= 0.3L = 100mm

a = 10mm

b = 10mm

F = 100N

Objective:

Compute the maximum deflection and locate

point of maximum deflection

Tasks:

How should this be modelled?

Compare results with results obtained

from beam theory?

Topics:

Element type, Real constants, modeling,

Plot results, output graphics

Example Comments/Questions

What did change compared to the Beam

model?

The example0300.lgw can be edited inNotepad

What are the assumptions in this case?

Will the shape or the number of elements

affect the solution?

File menu

Clears (zeros out) the database stored in

memory. Clearing the database has the same

effect as leaving and reentering the ANSYS

program, but does not require you to exit.

You can include commands to be

executed when the program starts up in

the start71.ans file.
