Arclength method non linear fea

AI Thread Summary
The discussion focuses on understanding the arc length and line search methods in the context of nonlinear finite element analysis (FEA), specifically comparing them to the Newton-Raphson method. It addresses the updating of the stiffness matrix and the general procedures involved in these methods. The conversation also references arc length continuation as a key concept in nonlinear FEA. A specific resource mentioned is "Applied Nonlinear Dynamics: Analytical, Computational, and Experimental Methods" by Nayfeh, which may provide further insights. Overall, the thread seeks clarity on the application and methodology of these nonlinear analysis techniques.

i would like to understand the arc length and line search method against Newton raphson method


how the stiffness matrix updation and the general procedure is done


my question is with reference to non linear fea

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
