hi all,
How to decide the geometric nonlinearity?.
i.e If i consider a sturcutre for example-fishing rod or wind turbine blade, how to decide that the structure is geometrically nonlinear.
Does it requires lots of calculations or by experimentation... For example by just observing the structure, is it possible to decide?
What are the reasons to consider the geometric nonliearities.
Regards

Hi!
I am trying to solve (for equilibrium points) a geometrically nonlinear problem of the form
f(u) = F
where u is the displacement and F is the load. At first I tried the plain
Newton method, with, perhaps obviously, limited success. I then tried to use
linesearch and trustregion strategies to improve the situation. Eventually, however,
I realized that I needed to use some form of continuation method. Though the most
commonly used methods in mechanics seems to be based on gradually increasing the
A PhD scholarship is available at DTU Mechanical Engineering, Technical University of Denmark in the field of micro mechanical modelling of composite materials for wind turbine blades. The department has well-established research activities within material modelling and composite mechanics.

At the department of Materials Science at Monash University, we have two openings for Ph.D student positions starting immediately in the general area of Computational Mechanics/Materials Physics. The material systems that we are interested in—for example, graphene, semiconductor nanowires and quantum dots—are relevant for nanotechnology and energy applications. The current research topics are multidisciplinary in nature, with underlying principles drawn from Mechanics and Condensed Matter Physics.
