Nonlinear Geometry and Large Displacement Analysis - FEA using ANSYS - Lesson 7

This tutorial focuses on conducting large displacement (also known as nonlinear geometry) analysis, and what scenarios this type of analysis is merited.

Learning objectives:
1. Change analysis settings so large displacements are taken into account.
2. Identify when large displacement analysis is required.
3. Define time-stepping and iteration settings in order to conduct nonlinear analysis.
4. Describe P-Delta effects and how large displacement analysis incorporates these effects into the solution.

Dr. Hedegaard, I cannot express how thankful I am that you have uploaded such a wonderful tutorial series for the public. I never learned any FEA softwares besides ABAQUS at UT Austin during my master's and I often felt disadvantaged in job hunts. Again, these lectures are amazing and I am thankful that you decided to share your passion.

Thank you so much doctor
I work on structural in Babol nooshirvani university of technology in iran, your video is really great
Have a good day

Thank you so much sir, this tutorial really helped me a lot.

thank you so much for your comprehensive lesson, I was wondering if the large deformation can be done on static analysis with a imperfection model?, much appreciated your answer.

Greetings Prof. H i have a question how the axial load caused the end moment to become almost Zero . what i understand is that the applied axial load should have increased the End moment as the deformation of the tip is upward which will cause an additional moment in the same direction
