Buckling and snap-through: stability of thin-walled structures
Imperfection is required here
Learn how to use Ansys Mechanical to determine bifurcation and ultimate loads as well as the post-buckling behavior of your structures. This training is offered as a 1-day course or alternatively as a self-paced eLearning course.
Duration
1 day
Prerequisites
Basic knowledge of Ansys Mechanical
Software used
Ansys Mechanical
- Your basis for numerically supported investigations of buckling prone structures
- Evaluate and optimize the stability of your structure
- Understand and overcome convergence problems in ultimate load analysis
- Analyze thin-walled structures with geometric imperfections
Description
If you are entrusted with the design of thin-walled structures, whether load-bearing structures in steel, plant or crane construction, components of household appliances or even snap domes, this seminar will provide you with the necessary knowledge for the safe application of Ansys. This is because high material strengths enable slender and therefore lightweight structures, but these tend to fail under compressive loads, so that the stability must be examined.
Eigenvalue buckling analyses and ultimate load analyses can be used for this purpose. While eigenvalue buckling analyses "only" allow the determination of bifurcation loads and the associated buckling mode shapes, ultimate load analyses enable a calculation of the load deformation behavior and thus the ultimate loads by taking large deformations, plasticity and imperfections into account. This seminar prepares you to familiarize yourself with numerically supported verification concepts, for example according to Eurocode or ASME.
Participants of this course should be familiar with the use of Ansys Mechanical and with nonlinear analysis, especially the topics of large deformations and plasticity, but also the basics of stability, to achieve maximum learning success.

Whether eLearning, classroom courses, live online training or customized workshops - together we identify the best option for you.
Do you have questions on the training or the eLearning?
If you book through your university, you will receive a 50% discount on the stated fee on training courses and eLearning courses.
For more information on the validity and how booking with the code ACADEMIC50 works, please visit our page on training for academic users.
Straight after you sign up, an automatic confirmation of receipt will be sent to the email addresses you provided. Once you have successfully verified the data you provided, you will receive your personalized sign-up confirmation, containing further information on course fees, the billing address, etc., by email within two to three working days.
As soon as the minimum number of attendees has been reached, you will receive a final training confirmation containing further information. If you have booked an on-site training, we recommend that you wait until you have received this final confirmation before booking your travel and accommodation.
If the minimum number of attendees is not reached, we reserve the right to cancel the training seven days before it is due to start at the latest. We are happy to inform you on changing your booking to an alternative date. Please note that we accept no liability for hotel or travel bookings that attendees have already made.
Usually the training courses start at 9:00 am and end at 5:00 pm of the respective local time. The actual course times will be stated in the booking confirmation. Please note that, depending on the training host, there may be a possible time shift between your and the provider's local time. Therefore all local times are provided with the valid time shift to Greenwich Mean Time (GMT).
To get a clear impression of our online learning format, we offer you a trial allowing you access to the starting module of an eLearning course of your choice. No costs, no cancellation period or anything similar. Moreover, with this free test access you can check all the technical requirements for a smooth learning process. You can easily request the free module from any eLearning course.
Each online course day comprises four eLearning modules. You should ideally allow 90 to 120 minutes of uninterrupted learning time for each module. This will allow you to acquire the knowledge provided by a module and to consolidate it through quiz questions and Ansys exercises. By dividing each module into micro learning units, you can also make good use of smaller time windows, such as on your commute.
Prerequisite for the use of the eLearning courses is the use of a personalized access to the CADFEM learning platform.
When purchasing an eLearning course, access to the learning platform is 365 days.
As a subscription user, access to the learning platform starts and ends with the start and end of the subscription.
With the purchase of a further learning product (learning subscription, training, eLearning), you will receive renewed access to all previously booked content for 365 days, starting from the start date of the new learning product.
