Problem 1: Part 2: Plate with Uniform Load Analyzed Using Symmetry Conditions

Problem Description

In this part, we will work on the same plate as we modeled in part 1, but we will use symmetry conditions to solve the problem by considering only the top right quarter of the plate.

# Material : The plate 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 plate is constrained from displacing in the x direction on the left side, and is constrained from displacing in the y direction on the bottom side.
# Loading : Uniform tensile Load with magnitude 20,000 lb/in^2 acting on the right side of the plate.
# Objectives : To solve the same problem from problem one using symmetry conditions.
# Things to hand in :

1. Query Stress xx
2. Query Strain xx
3. Query Strain yy
4. Query Displacement in x direction
5. Query Displacement in y direction
6. Plot Stress xx VS. y
7. Plot Stress yy VS. y
8. Plot Shear stress xy VS. y
9. Combine 6, 7, 8 in one plot

After you 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 plate should appear on your ANSYS GRAPHICS window.
