Foreword
Injustover threedecades,“Computational modelingofmaterial formingprocesses” hasevolvedina tremendous and sometimesunexpectedway,frommeshescontainingafewdozenelementswithsimplematerialbehaviorslikerigid-plastic ones to millions ofdegrees of freedom simulations dealing withextremely complex constitutive models andcombining severalphysicsatdifferentscales.
TheseriesofinternationalconferencesICOMP–Internationalconference onCOmputationalmethods inManufacturing Processes–thatwassuccessivelyinitiallyheldinSaint-Étienne,France(2014),andtheninLiège,Belgium(2016),andwhich willtakeplaceinBarcelonanextSeptember2018,intendstocovertheevolutionofthisimportantscientificdomainandto presenthigh-levelscientificadvancesbothtotheacademiaandtheindustrialworld.
