Problem
1 : Beam with Uniform Load
Problem Description
# Material : The beam is made of steel
with Modulus of elasticity E = 30,000 ksi, and Poisson's ratio = 0.3
# Unit : U.S. Customary Units ONLY. It
is important to convert all forces to "lb" and all dimensions
to "in".
# Boundary Conditions : The beam is constrained
along X on the left side, and is constrained along Y on the bottom
line.
# Loading : Uniform tensile Load with
magnitude 20,000 lb/in^2 acting on the right side of the beam.
# Objectives :
1. To determine stresses, strains and displacements on
nodes when the load is applied to the beam.
2. To model the beam with coarse mesh (1 element) and fine mesh
(4 elements), and determine how the element resolution affect the
stresses, strains and displacements.

The input box
"CREATE RECTANGLE BY DIMENSIONS"
should now appear on the screen. According to the Problem statement,
we will have to create a beam with dimension 2 inches long and 1 inch
high. Enter the corresponding x and y coordinates in the box like
the figure shown below.
Note: Since this example can be modeled as a plane stress problem,
it is easier to create the beam as a two dimensional area instead
of a volume. If not specified otherwise, ANSYS assumes a thickness
of 1 in. into the screen.
After finish entering all the values, click
OK.
(DO NOT click Apply and then OK. This will place two rectangles
in that location!)
Now the blue rectangular beam should appear on your ANSYS GRAPHICS
window.
