FEA on Tyres
I have heard that it is difficult to perform finite element analysis on automobile tyres ? If so how ? (I am quite new to the subject). Is it because of the shape which makes dividing into elements difficult or the material used ?

Ramani AswathRubber is an elastomer. Difficult to study using linear methods. The reinforcement also adds an extra dimension to the problem.
Non linear methods are available. Some info is available in this white paper:

NAVATHE SACHINyes u r ryt ..circular shapes of tyres make meshing operation difficult mostly v opt for "quad elements(rectangular or square shaped elements) for meshing purpose.this quad elements are not properly spread near the centre area of tyres and they tend to become triangular element by the time they reach centre from circumference line .this makes job more difficult.

Amith Guptacould take a sector..quad/hex mesh it and make a cyclic symmetry model. anyhow doesnt' the hyperelastic condition interfere?
