Training Course: Contact Analysis (20 - 21 October 2025)

Contact Analysis

After a short theoretical introduction to contact analysis, the participants learn how to contact definitions in PERMAS are implemented and how they can be used. The various modeling options for contacts (node or surface contact) are discussed in detail. The participants receive tips and hints on how to choose the best way to model the contact based on their problem.
The numerous contact results made available by PERMAS are presented and discussed. In addition, it will be explained how these results are to be interpreted and what possibilities they offer to check the model for plausibility. The topic of the storage of rigid body modes, which are held by contact forces during the analysis, are treated. In particular, the CAZERF elements (zero force springs) are presented and discussed.
Another focus of the training is the contact geometry update. The definition in PERMAS is presented. Practical examples are shown, possible pitfalls are discussed and practical solutions are shown. The definition of non-linear load histories for PERMAS is discussed and the screw preload will be introduced briefly. The exercises offer the participants room for discussions and the possibility to put into practice what they have learned. In addition, they receive practical tips and thus learn how to apply the newly gained knowledge to own models.
It is recommended to attend this training course together with the PERMAS basic training.
