Finite Element Analysis Assignment 2

GEOMETRY

Describe how the geometry was created. Present the geometry of your part, including dimensions.

MESH

Describe how the geometry meshed. You may include figures. The figures should be approximately 8 cm wide. The caption for a figure should be placed below the figure.

Describe how the boundary conditions are applied and how the component is loaded.

In this assignment, you will use Ansys Workbench to model a thin rectangular steel plate with a centre hole. Both tension and bending loading conditions will be modelled, as shown in Figure 1.

The length and width of the plate are l and b, respectively, and the diameter of the hole is d. The area of the rectangular plate with a centre hole is the number formed by the first five digits of your student ID in mm2

. For example, if you student ID is 24317985, the area will be 24317
mm2 . The length, l, should be approximately twice the width, b. In addition, the ratio d/b should be between 0.1 and 0.3. You should create your plate as a 2D surface. Zero marks will be awarded to 3D solid models. You may take a reasonable number for thickness.

In addition, you should apply techniques that you have learned in Practical Considerations to simply your models.

For both tension and bending loadings, select a suitable analysis to obtain the stress distribution, which can be represented by a contour plot. In addition, find the maximum stress and location.

For both loading conditions, you will need to perform a convergence test. Finding the stress concentration factor is optional.

For both tension and bending, add geometric features (e.g., auxiliary holes) to reduce stress concentration. Present a comparison between the improved and original designs.
