  1. Idealization – Models and Elements There are two types of idealizations: Model Idealization A 3D model is simplified 2. Element idealization Other than the 3D elements are used

  2. 3D Models Load is applied normal to any of its flat surface or axis.

  3. 2D Plane Stress Models

  4. 2-D Plane Strain Models

  5. Axisymmetric Models

  6. Element Idealization • Saves Run Time • The default element is 3-D • Most FEA use Idealized Elements

  7. Idealized elements • Beam: 1-D element

  8. 2-D Solid: Surface Element

  9. Shell: Surface or Line element

  10. Spring: No mass

  11. Mass: No stiffness
