Element Quality

This metric is based on the ratio of the volume to the sum of the square of the edge lengths for 2D quad/tri elements, or the square root of the cube of the sum of the square of the edge lengths for 3D elements. 

This can also be expressed as follows:
• For two-dimensional quad/tri elements:

• For three-dimensional brick elements:

The following table lists the value of C for each type of element:

• The Element Quality option provides a composite quality metric that ranges between 0 and 1. 
• A value of 1 indicates a perfect cube or square while a value of 0 indicates that element has a zero or negative volume.

Problem 2: 3D analysis of a plate with hole in center

A square plate with a hole at the center is under a tension load p in x direction as shown in the figure below. the dimension of the plate is 10in X 10in, thickness is 0.1in, and radius of hole is 1 in. Assume material structural Steel and p = 100 psi. FInd the maxium stress in plate.

Result:- 

1. Deflection(total )

2. Deflection( x- direction)

3. Deflection( y- direction)

4. Stress(von-Mises)

5. Strain(von-Mises )

6. Stress concentration factor

justify your answer with correct explanation, applying your subject knowledge.
