How is plastic behaviour in metals simulated and used in practical engineering applications?
What are potential difficulties and challenges in modelling plasticity problems using FE software?
What are the potential errors and limitations of the FE plasticity solutions?
This course gives you practical advice with a minimum of theory.
This eLearning course is aimed at engineers and designers who want to learn about how plastic behaviour in metals is modelled using FE software.
The course will cover plasticity theories that are widely used to analyse practical engineering applications in metals. Mathematical formulations and equations are intentionally kept to a minimum. Emphasis will be placed on how engineering design incorporates these theories and how the FE method models plasticity.
Difficulties encountered by both the FE user and the FE software in modelling plasticity will be highlighted using many examples to demonstrate plastic behaviour and how to assess the accuracy of the FE solutions.
The pre-requisite for this course is a working knowledge of linear finite element theory and applications. No prior knowledge of plasticity theory is required. The course is independent of any FE software code.
Travel and training budgets are always tight! The e-Learning course has been developed to help you meet your training needs.
If your company has a group of engineers, or specific training requirements across any subjects, please contact us to discuss options.
This is a three-week live web-based eLearning course with a total of 6 hours of tuition (presented as a two-hour session per week). Delegates will be provided with copies of all lecture slides including many self-test problems (with worked solutions).
Self-test questions (optional homework)- Questions to reinforce the topics covered in the lectures
Solutions to self-test questions (Full solutions highlighting the key aspects)
More Self-test questions (optional homework)

"Super! Doesn't get better than this. Good idea to start having e-Learning courses."
"I'm really happy not to pay a big fraction of my annual training budget to airlines and hotels. A BIG plus to e-learning."

*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.
