This special issue of IJFP contains selected extended papers from the 7th
ESAFORM Conference held in Trondheim, Norway in April 2004. This annual
conference travels through Europe and gathers scientists from academic, research
institutions and industry. More than 200 participants discuss about different
material forming processes and bring their expertise either on experiments,
numerical developments, simulations or production. The papers with a good balance
between theoretical models, numerical simulation and experimental verification,
satisfying requirements of relevance and scientific qualities have been selected.
