    • Surface wave in a Maxwell liquid-saturated poroelastic layer 
      Article dans une revue avec comité de lecture
      ccLE POMMELLEC, Jean Yves; ccEL BAROUDI, Adil (Elsevier, 2020)
      An analytical approach of the propagation and attenuation of Love waves in a viscoelastic liquidsaturated poroelastic layer has been considered in this paper. The equations of motion have been formulated separately for ...
    • Multireflection grazing incidence diffraction used for stress measurementsin surface layers 
      Article dans une revue avec comité de lecture
      MARCISZKO, M; WROBEL, M; SEILER, W; DONGES, J; SNIECHOWSKI, M; WIERZBANOWSKIA, K; BACZMANSKI, Andrzej; ccBRAHAM, Chedly (Elsevier, 2013)
      The geometry based on the multireflection grazing incidence X-ray diffraction can be applied to measure residual stresses. Using this method, it is possible to perform a non-destructive analysis of the heterogeneous stresses ...
    • Quadratic solid‒shell elements for nonlinear structural analysis and sheet metal forming simulation 
      Article dans une revue avec comité de lecture
      WANG, Peng; ccCHALAL, Hocine; ccABED-MERAIM, Farid (Springer Verlag, 2017)
      In this paper, two quadratic solid‒shell (SHB) elements are proposed for the three-dimensional modeling of thin structures. These consist of a twenty-node hexahedral solid‒shell element, denoted SHB20, and its fifteen-node ...
    • Key Characteristics identification by global sensitivity analysis 
      Article dans une revue avec comité de lecture
      IDRISS, Dana; BEAUREPAIRE, Pierre; GAYTON, Nicolas; ccHOMRI, Lazhar (Springer Verlag, 2019)
      During the design stage of product manufacturing, the designers try to specify only the necessary critical dimensions or what is called “Key Characteristics”. Knowing that dealing with Key Characteristics is time consuming ...
    • Numerical Predictions of the Occurrence of Necking in Deep Drawing Processes 
      Article dans une revue avec comité de lecture
      ccCHALAL, Hocine; ccABED-MERAIM, Farid (MDPI, 2017)
      In this work, three numerical necking criteria based on finite element (FE) simulations are proposed for the prediction of forming limit diagrams (FLDs) for sheet metals. An elastic–plastic constitutive model coupled with ...
    • Curvature radius measurement by optical profiler and determination of the residual stress in thin films 
      Article dans une revue avec comité de lecture
      ccBESNARD, Aurélien; ARDIGO, Maria-Rosa; IMHOFF, Luc; ccJACQUET, Philippe (Elsevier, 2019)
      The Stoney formula, based on the measurement of the substrate curvature, is often used for the determination of the thin films' residual stress. In this study, titanium nitride coatings were deposited by DC reactive magnetron ...
    • Maximum length scale requirement in a topology optimisation method based on NURBS hyper-surfaces 
      Article dans une revue avec comité de lecture
      COSTA, Giulio; ccMONTEMURRO, Marco; ccPAILHES, Jerome; ccPERRY, Nicolas (Elsevier, 2019)
      This paper deals with a new method for handling manufacturing and geometrical requirements in the framework of a general Topology Optimisation (TO) strategy. In particular, the maximum length scale constraint (MLSC) ...
