    • On the detection of over-constrained subparts of configurations when deforming free-form curves 
      Communication avec acte
      HU, Hao; ccPERNOT, Jean-Philippe; ccKLEINER, Mathias (2016)
      Today, designers use CAD modelers to define and modify NURBS surfaces involved in the design of complex shapes like car bodies or turbine blades. The generated shapes often result from the use of variational modeling ...
    • Reusing heterogeneous data for the conceptual design of shapes in virtual environments 
      Article dans une revue avec comité de lecture
      LI, Zongcheng; GIANNINI, Franca; FALCIDIENO, Bianca; ccPERNOT, Jean-Philippe; ccVERON, Philippe (Springer Verlag, 2016)
      Today, digital data such as 2D images, 3D meshes and 3D point clouds are widely used to design virtual environments (VE). Most of the time, only one type of those multimodal data is used to describe and specify the shapes ...
    • A three-level signature by graph for Reverse Engineering of mechanical assemblies 
      Communication avec acte
      BRUNEAU, Marina; DURUPT, Alexandre; VALLET, Laurent; ccPERNOT, Jean-Philippe; ccROUCOULES, Lionel (2016)
      Several approaches exist to provide Reverse Engineering solutions on mechanical parts. Mechanical assemblies and the expertise information retrieved at the same time with the model geometry are not really taken into account ...
    • Incorporating free-form features in aesthetic and engineering product design: State-of-the-art report 
      Article dans une revue avec comité de lecture
      FALCIDIENO, Bianca; GIANNINI, Franca; LEON, Jean-Claude; ccPERNOT, Jean-Philippe (Elsevier, 2008)
      The use of free-form shapes has become mainstream to design complex products that have to fulfil engineering requirements as well as aesthetic criteria. Even if today’s CAD systems can easily represent free-form shapes by ...
    • Automatic extraction of assembly component relationships for assembly model retrieval 
      Article dans une revue avec comité de lecture
      LUPINETTI, Katia; GIANNINI, Franca; MONTI, Marina; ccPERNOT, Jean-Philippe (ELSEVIER, 2016)
      Even if during the Product Design Process, assembly models are described in terms of their constitutive components and associated relationships, only the position of each component is often stored within the Digital Mock-Up. ...
    • A finite element/quaternion/asymptotic numerical method for the 3D simulation of flexible cables 
      Communication avec acte
      COTTANCEAU, Emmanuel; ccTHOMAS, Olivier; ALOCHET, Marc; DELIGNY, Renaud; ccVERON, Philippe (ICTAM, 2016)
      A flexible cable is modeled by a geometrically exact beam model with 3D rotations described using quaternion parameters. The boundary value problem is then discretized by the finite element method. The use of an asymptotic ...
    • Iterative surface warping to shape craters in micro‐EDM simulation 
      Article dans une revue avec comité de lecture
      SURLERAUX, Anthony; ELKASEER, Ahmed; BIGOT, Samuel; ccPERNOT, Jean-Philippe (Springer Verlag, 2016)
      This paper introduces a new method for simulat- ing the micro-EDM process in order to predict both the tool’s wear and the workpiece’s roughness. The tool and workpiece are de ned by NURBS patches whose shapes result from ...
