| Abstract |
A 3-D solid finite element simulation of sheet forming processes is briefly discussed.
Examples of cold or warm deep-drawing and sheet hydro forming are presented. Sheet work-pieces
can be assembled to produce complex components by using different techniques: such as welding or
mechanical fastening. They must also be simulated in order to evaluate and optimise the quality of
the parts; examples of hemming and of self piercing riveting are described. Structural computation
allows us to evaluate the strength of a component and especially the strength of the joining. In the
future, more precise optimization of the components will be possible by the transfer of data from
the previous stages of sheet forming and joining, to the structural computation code. This input data
will be firstly the distribution of residual stresses, the evolution of local properties such as elastic
limit, damage and anisotropy. An example of structural computation on a system of two sheets
assembled by a single rivet is presented. |
