This course is in an example-based format for 2D Finite Element Analysis (FEA) using PYTHON.. By joining this course, you will learn following main skills:

• Fundamental theories and formualtions in 2D FEA.

• Mastering theories and formualtions for linear 4-node Quadrilateral element (Q4), linear 3-node Triangular element (T3), and Quadratic 8-node Quadrilateral element (Q8).

• Write FEM codes in PYTHON for Q4, T3 & Q8 elements for difenent interesting 2D problems.

• A comprehensive study on mesh convergence for Q4, T3 and Q8 elements.

• A comprehensive comparison on the performances (accuracy vs computational cost) of Q4, T3 and Q8 elements.

• Full 35 slides including theories and formualtions are available to download.

• PYTHON FEM codes for all examples are available to download for further study.

• All formulations and Python codes are explained.

This fundametal course is part I (basic level in FEM) in my two-level courses for 2D FEA. When you finish this course, you may consider joining another 2D FEA course (part II – intemediate level) where you will learn many more interesting things such as: stress & strain calculations, coupling degree of freedoms in FEA, mesh refinement, multi/composite material structures, etc. By completing these two courses, you will obtain significant knowledge in FEA, especially for 2D structures.
