All physical systems in the real world are inherently nonlinear in nature. Hence, one of the most difficult tasks facing an engineer is to decide whether a nonlinear analysis is really needed and if so what degree of nonlinearity should be applied. The majority of FEA carried out within the aerospace industry will be based on well proven linear assumptions. However, there will be situations where a nonlinear analysis is required to adequately describe the physical situation.
Nonlinear behavior can take many forms and the appropriate FEA simulation methods can be challenging.
An attachment fitting may develop significant change in stiffness and load distribution path due to ‘heel and toe’ response. A skin panel may develop complex deformed shapes as it initially buckles and transitions from shear to diagonal semi-tension.
Perhaps the assembly is being checked for an ultimate condition and we need to check that plastic growth is stable and there is no failure – bent but not broken!
Whatever the challenge, the objective of this course is to break down the nonlinear problem into clearly defined steps, give an overview of the physics involved and show how to successfully implement practical solutions using nonlinear Finite Element Analysis.

About the Instructor
Tony Abbey has created and taught a wealth of FEA training material over the past 20 years. Thousands of engineers across the world have benefited from his live and e-learning based classes. He has developed a reputation for providing the student with an experience that is full of insight gained from his extensive experience, but which also challenges and motivates.Tony has been working with FEA for nearly 40 years, both in Industry and for leading FEA software providers in the UK and the US.
His informal and interactive presentation style allows the key concepts to be taught in a manner which involves participants fully in the course material. Tony presents papers at NAFEMS and other conferences on a regular basis and has been involved with NAFEMS since its formation. He has written a series of very popular articles on FEA for Desktop Engineering magazine.
