Abstract
The paper deals with problem linked to finite element analysis of airframe crash
study. Today the limit of Finite Element analysis imposes a minimum shell
element size which does not represent local failure due to riveted joints. These
local failures are generally critical and it leads the global ruin mode of airframe
during crash.
It is difficult to find a compromise between computation time (relative to size of
model, size of elements, numerical power of tools) and prediction of simulation
linked to thin description of geometry which influence genera
