This course is your starting point towards really understanding solid mechanics. You need to understand the basics to enable you to apply good practice in your finite element analysis, and this course will give you the knowledge you really need for a good understanding of the principles that every engineer or designer should know.
You don't need in-depth knowledge about FEA or computational simulation. A working knowledge of engineering design and analysis is all you need to start out with.
You will learn about the solid mechanics and basic theories that are widely used in engineering design, analysis and simulation.
Each session is a building block - over the five weeks, you will cover:
The course covers these topics in a concise and practical manner. Unlike traditional university courses, this course avoids lengthy mathematical derivations and highlights many practical examples to illustrate the application of solid mechanic theories in modelling and analysing engineering structures. Where possible, exercises that can be done by hand are included so that attendees can test their knowledge. Full solutions will be provided within a few weeks of completing the course.
The course is completely code independent.
This is a 5-session online training course, with each session lasting approximately 2 hours, depending on homework submissions, questions & discussions.
You can attend the sessions live, and/or stream on demand. For additional info on telephony charges please email e-learning @ nafems.org .
A full set of notes in PDF format will be available for download.
Personal passwords are provided to allow you to access e-learning backup material via our discussion forum. Reading lists, homework submissions and supplementary information are all available via the discussion forum.
To get the most out of the course, participation in forum discussions is very much encouraged. Typically the forum remains open for 4 weeks after the last live session, giving you plenty of time to catch up with homework, review and ask questions.
Note: homework is purely voluntary
This set of courses is important for designers and engineers who wish to gain a good understanding of the basic solid mechanics:
Mechanics depends upon an understanding of statics where motionless bodies of any shape, size and material are considered to be in a state of equilibrium under the action of external forces (session 1).
These bodies are deformable and hence undergo strains and stresses. By understanding the stress capacity of a body we can understand the load that it can carry and support (session 2).
However, each material behaves in a different way so that building a component from steel is very different than building it from plastic. Decisions on material usage requires an understanding of the constitutive or material relationships (session 3) so that the developing stresses when the body undergoes straining can be calculated.
In our desire to determine stresses in a certain component made of a certain material many hand calculations have been developed historically based on laboratory studies and in-field readings but understanding their presentation and their limitations is important (session 4).
Many components are part of larger systems and a very important part of understanding the statics is the understanding of the externally applied loads and boundary conditions or external restrictions that may exist (session 5).

*It is your individual responsibility to check whether these e-learning courses satisfy the criteria set-out by your state engineering board. NAFEMS does not guarantee that your individual board will accept these courses for PDH credit, but we believe that the courses comply with regulations in most US states (except Florida, North Carolina, Louisiana, and New York, where providors are required to be pre-approved)
Telephony surcharges may apply for attendees who are located outside of North America, South America and Europe. These surcharges are related to individuals who join the audio portion of the web-meeting by calling in to the provided toll/toll-free teleconferencing lines. We have made a VoIP option available so anyone attending the class can join using a headset (headphones) connected to the computer. There is no associated surcharge to utilize the VoIP option, and is actually encouraged to ensure NAFEMS is able to keep the e-Learning course fees as low as possible. Please send an email to the e-Learning coordinator (e-learning @ nafems.org ) to determine if these surcharges may apply to your specific case.
Just as with a live face-to-face training course, each registration only covers one person. If you plan to register a large group (10+), please send an email to e-learning @ nafems.org in advance for group discounts.
