Problem 2.

The cantilever beam pictured is rigidly

supported (fixed) at its left-end and is subject to

forces F, and F, applied to its right-end. Perform

a finite element analysis of this beam subject to

the following guidelines.

Material: AISI 1045 Steel cold drawn

External Load:

.

Assign an axial Force F-840 N that acts

Normal to the right-end of the beam in the

direction shown.

b)

Also, apply an upward Force F,-740 N that

acts on the top-right Edge of the beam.

Assign a Fixed restraint to the left-end

(left-end face) of the beam

y

Diameter.1m

Length 5 m

Determine the following:

a) Use the Probe feature to create a graph of o, across the front face of the beam (from top

to bottom) at approximately X=0.04 m to the right of the fixed-end. Use classical stress

equations to calculate the appropriate normal stress on both the top and bottom surfaces of

the beam and compare the percent difference.

Calculate the maximum shear stress due to bending using classical equations at the fixed

end and compute the percent difference between classical and finite element solutions for

maximum shear stress determined half-way between top and bottom surfaces of the beam.
