PRESENTATIONOFTHERESEARCHLAB
ICB lab (Laboratoire InterdisciplinaireCarnotdeBourgogne) is a researchunitof theUniversitédeTechnology de Belfort-Montbéliard (UTBM). In this institute, COMM department works on thefollowingresearchissues:
• Proactivedesignofmechanicalsystemsbyusingthetheoryofspatiotemporalmereotopology,so as to provide a better integration, efficiency and flexibility in the product developmentprocess;
• Additive manufacturing and the different underlying processes and the development ofspecificmaterials.
Therefore,thisPhDthesisproposalispartofacross-sectoraltheme(designofproduct-process-materialinteractionincludingintelligence),fullyinnovativeregardingcurrentscientificissueswithintheinternationalcommunity.
DESCRIPTIONOFTHEPHDSUBJECT
Over the last two decades, manufacturing industry has been progressively forced to increaseproduct/system capabilities and compact its lifecycles by ensuring a certain level of flexibility andefficiency as competitive edges, especially in the development phase where design activities anddecisionshaveagreatimpactondownstreamprocesses(i.e.manufacturing,assembly,etc.).Thishasbeensuccessfullyachievedbyconsidering(i)thecaptureandintegrationoflifecycleconstraintsandknowledge(e.g.designforX–DFXspectrumapproaches,advancedComputerAidedDesign–CAD)inmechanical product design so as to deliver lifecycle friendly products, (ii) the integration of otherdisciplines such as electronic inmechatronic product design and (iii) the integration of computingcapabilityintheeraoftheInternetofThingsforconnectedobjects(seegreyboxesinFigure1).

new design tools are needed to fully take advantage of the complex dynamics, multi-materialprogrammability,self-assemblyandself-reconfigurationbehaviors,anddomain-specificknowledge.Insuchaway,thefactofdesigningandmanufacturingprogrammableproducts/systems–abletoevolveindifferentcontexts(e.g.statetransformation,kinematic,form,etc.)toprovideanappropriateservicetothefinaluser–willrequireengineeringandmanufacturingresearcheffortsatdifferentlevels,suchas product/system level (mechanical structure to smart systems), process level (traditionalmanufacturingtoadditivemanufacturing)andmateriallevel(traditionalmaterialtosmartones).
Thedefinitionofphysicalobjectsandtheirrelationshipsoverspaceandtimerequiresacommonsenseengineering approach, also called transdisciplinary approach, that concerns and governs manydisciplines in a top-down fashion. Indeed, this crucial issue is currently tackled from variousperspectives in thedomainsof geomatics, computer science, engineeringandmaterials science tonameafew,butaharmonizationisneededtofullyembrace4Dprintingandprogrammablemattercapabilities.Actuallybothpromisingtechnologiesaddressthespatialchange(i.e.configuration,shapeandphysicalproperties)ofphysicalobjectsovertimebutwithspecificapproaches,whichneedtobealignedandadopted froma semanticand logicalpointof view for further computational issues indesignofsmartproducts/systems.
4Dprintingisbasedupontheinteractionofadditivemanufacturingandsmartmaterialssoastobuildactive/livingobjectswithexternal stimuli (e.g. temperature,pH, light,electricity,mechanical force,magnetic force, etc.). As for programmablematerial,matter has the ability to change its physicalproperties(e.g.shape,density,opticalproperties,etc.) inaplannedmannerbasedonautonomoussensing. Such promising concepts tackle a common issue but at different hierarchical levels (i.e.building,physicalobject,material,etc.).Therefore,itbecomesvitaltoestablishaconcretesemanticandlogicalfoundation,onwhichseveralstakeholdersfromvariousresearchfieldscanreferto.
