Projects

 

Final Projects:

The course will end with a final project involving either the application or the development of the finite element method to a problem of your choosing.

 

Preliminary Project Proposals: will be due Nov 22. The proposals should specify the problem you will solve in sufficient detail to leave only coding/analysis to be completed. This means you must specify

    1. The governing equations that will be solved (constitutive model, and/or field equations)
    2. The numerical approach to solving the equations (discretization in time/space).
    3. The boundary / initial value problems that will be solved - specify boundary conditions; what will be computed/plotted; ranges of property values that will be considered; and discuss dimensional analysis of the problem to be solved (what are the relevant dimensionless groups that determine the solutions?)

Final Projects will be due December 15.

 

Extensions on project deadlines are permitted, but if more than two deadlines are missed during the course of the semester it will reduce your final grade.

 

Project suggestions:

FEA coding based projects

    1. Implement one of the elements that were discussed in class but which were not coded in a homework assignment (eg hybrid elements, or a finite strain B-bar elements)
    2. Extend the Cahn-Hilliard diffusion problem solved in HW8 to consider plastic deformation, and add boundary conditions that will allow you to prescribe fluxes on exterior boundaries. You could use your code to simulate Li insertion and diffusion in a plastically deforming Li-ion battery electrode.
    3. Extend the continuum beam element implemented in HW9 to finite deformations
    4. Implement a 3D membrane, beam, plate or shell element in EN234FEA or as an ABAQUS UEL (will require independent research to learn how to handle beams, plates and shells)
    5. Implement a 2D grain boundary diffusion element as an ABAQUS UEL or in EN234FEA using the procedure described in this reference
    6. Implement an advanced material model - eg viscoelasticity; finite strain viscoelasticity, crystal plasticity (hard) as a UMAT or VUMAT

FEA Analysis based projects

    1. Set up an FEA model of a 'Galilean Cannon' (we have one- you could compare you predictions with high-speed video, although our cameras are only capable of 1200 fps which may not be sufficient). You could try using ABAQUS to optimize the design (see also this demo from an old Colbert show)
    2. Solve a boundary value problem relevant to your research
    3. Design a set of boundary value problems intended to test the capabilities of the ABAQUS element library
