    Meshed 3D Model Example AUTODESK UNIVERSITY 2015 A AUTODESK.

  16. Slide 16: Node Overview

    Node Overview  A node is a coordinate location in space where the Degrees of Freedom (DOFs) are defined.

  17. Slide 17: Element Overview

    Element Overview  An element is a mathematical relation that defines how the DOFs of one node relate to the next.

  18. Slide 18: Types of Elements

    Types of Elements  1D elements  A line connecting 2 nodes only for items like beams and springs  2D elements  Planar or axisymmetric elements with either three or four edges enclosing an area  Plates or Shell Elements: Planar elements that are triangular or quadrilateral with a specified thickn

  19. Slide 19: Element connectivity

    Element connectivity  Elements within a single part body can only communicate to one another via common nodes for transferring data information No Connection Connected Nodes

  20. Slide 20: Material Assignment

    Material Assignment  Material properties define the structure characteristics of the part  Material property information can be located at matweb.com Ultimate Strength Yield Strength • Failure (Elastic Limit) Force Strain Necking Area Hardening • • Stress = • • • • Change in Length • Strain = Orig

  21. Slide 21: Loads

    Loads Structural loads are forces applied to a part or assembly during operation and cause the model to displace, deflect, and induce stresses and strains

  22. Slide 22: Constraints

    Constraints Structural constraints restrict or limit the displacement of the model mesh nodes

  23. Slide 23: Contact Conditions

    Contact Conditions Contact conditions are used to establish relationships between the nodes of contacting parts within an assembly

  24. Slide 24: Simulation Solving

    Simulation Solving Running or solving the simulation processes and calculates the results based on the parameters established

  25. Slide 25: Results

    Results The simulation results can be viewed and exported as a report to make intelligent decisions

  26. Slide 26: Reviewing Results

    Reviewing Results  Simulation does not always replace the need for physical testing  The engineer / analyst still needs to interpret the results to make final decisions

  27. Slide 27: Displacement

    Displacement The displacement results show the magnitude of the model deformation from the original shape

  28. Slide 28: Von Mises Stress

    Von Mises Stress Formula for combining three principal stresses into an equivalent stress to compare to the material stress properties

  29. Slide 29: Safety Factor

    Safety Factor Provides a ratio of how much stronger the object is than it usually needs to be for an intended load Material Yield Strength Safety Factor = Maximum Von Mises Stress 40,000 psi 2 = 20,000 psi

  30. Slide 30: Convergence

    Convergence Convergence is the process of altering element sizes in high stress areas to ensure the specified result criteria has converged

  31. Slide 31: Stress Singularities

    Stress Singularities A localized high stress area where the stress becomes infinite resulting in distorted results

  32. Slide 32: Best Practices

    Best Practices  Ensure solution type (Linear / Nonlinear)  Setup simulation to match real world  Verify material properties  Avoid putting loads on nodes or small edges to avoid stress singularities  Ensure your results converge

  33. Slide 33: FEA Software

    FEA Software  Conceptual Simulation (Apps)  FEA Features Built into Design Tools  Purpose Built Simulation Software
