MEC4426/MAE3426: Connecting Lug - Mesh Convergence and Stress Singularity - Engineering Assignment Help

Assignment Task:

Question 1 Connecting lug 

Objectives: 

1. Learn to use Abaqus.

2. Understand mesh convergence and stress singularity. 

Perform the static analysis on Week 3’s connection lug problem with modified dimensions, as illustrated below. 

In your report, you need to submit the following results: 

1. Problem description.

2. Analyse the problem with 5 different mesh densities and show the meshes (without displaying the node labels or element labels).

3. Present the contour plots of the maximum principal stress for all the 5 models.

4. Draw a diagram to show the convergence of the maximum magnitude of the vertical displacement. Recommend which mesh should be used for the analysis.

5. A short discussion on your results (no more than 50 words).
