Practical Stress Analysis & Finite Element Methods

Three day course -
July 6th, 7th & 8th 2010

FEA has become widely used and universally accepted in many industry sectors. In order to derive maximum benefit from the available technology, engineers should learn about the many strengths of numerical techniques. At the same time, recommendations on how to avoid the inevitable pitfalls will prove invaluable at a later date.

NAFEMS, the only independent not-for-profit organisation with the aim of promoting the effective and reliable use of FEA, addresses this requirement by providing this three day example-driven, practical course. The course offers excellent guidance on how to judge which approximations are acceptable and appropriate for solving a wide range of practical problems. Of equal importance is the manner in which the results are interpreted. Advice is provided which allows the correct decisions to be taken, based on results which are known to be reliable. Interaction is encouraged throughout the course, with the planning and design of a complete FEA project and examples of simple hand calculations, mesh designs and solution designs being set for the class to complete. The course is completely code independent.


Who Should Attend?

This course is aimed at practising engineers who wish to learn more about how to start applying finite element techniques to their particular problems in the most effective manner. The material that is presented is independent of any particular software package, making it ideally suited to current and potential users of all commercial finite element software systems. This course is a must for all engineers aiming to use FEA as a reliable predictive tool for thermal, stiffness and stress analysis.

The course is open to both members and non-members of NAFEMS.

Course Programme

Day 1

The purpose of the first day is to revise the basics of stress analysis - the priority being the treatment of static problems with the use of free-body diagrams. These same diagrams will be essential to a well-planned Finite Element Analysis as they highlight the load path within the structure - this is paramount to our understanding of the problem and the generation of a reliable computer model.

  • Units and Conversions
  • Weight, Mass and Inertia
  • Free-Body Diagrams
  • Direct Stress and Strain
  • Shear Stress and Strain
  • Bending Stress
  • Thermal Stress Effects
  • Properties of Materials
  • Basics of Fatigue and Impact
  • Stiffness Calculations

Day 2

The purpose of the second day is to obtain an overview of what a modern-day Finite Element system can provide in terms of solution capabilities, treatment of non-linear effects and the likely accuracy that we can expect. Coupled to this overview, the internal workings of the method are exposed by solving simple problems in a long-handed fashion to properly undertand the primary unknowns, the reactions at constrained nodes, and the methods for calculating strains and stresses.

  • Basic Theory of FEA
  • Displacement and Load Control
  • Introduction to 1D FEA Problems
  • Introduction to 2D FEA Problems
  • Limitations of Linear Analysis
  • Boundary Non-Linearity
  • Material Non-Linearity
  • Geometric Non-Linearity
  • Introduction to 3D Problems
  • Processing CAD Data for FEA

Day 3

Day three examines the use of the Finite Element system in an industrial setting. This requires that sensible decisions are made in order to predict a realistic result in a reasonable amount of time and effort. Understanding the problem is paramount and a wide range of problems are solved in order to illustrate the changes in result that can occur when different assumptions are used. The third day also covers a basic introduction to contact and plasticity.

  • Design of Pressure Vessel FEA
  • Fast and Accurate Meshing Methods
  • Implementation of Natural Loads
  • Design of Realistic Constraints
  • Balanced Loads/Minimum Constraint
  • Statically Determinate Reactions
  • Application of Material Models
  • Hints and Tips for Contact Models
  • Worked Example with Plasticity
  • Results Interpretation and Checking
