  • Finite element modeling of porous solid propellants 

    Xu, F.; Sofronis, P.; Aravas, N.; Namazifard, A.; Fiedler, R. (2005)
    The effect of porosity on the constitutive response of a linearly viscoelastic solid that obeys a constitutive law of the standard differential form is investigated under small strain deformation conditions. It is demonstrated ...
  • Finite element modeling of trip steels 

    Papatriantafillou, I.; Aravas, N. (2004)
    In this paper, a constitutive model that describes the mechanical behavior of steels exhibiting the "Transformation Induced Plasticity" (TRIP) phenomenon during martensitic transformation is presented. Multiphase TRIP ...
  • General development of a new hall effect sensor 

    Petoussis, V. N.; Dimitropoulos, P. D.; Stamoulis, G. (2011)
    Silicon Hall plates show an offset of a few millitesla. A large portion of this offset is caused by mechanical stress in the device. The offset can be reduced with a factor 103 to 105 when the spinning - current principle ...
  • Introducing a new hall effect sensor - Novel dynamic offset reduction method 

    Petoussis, V. N.; Dimitropoulos, P.; Stamoulis, G.; Houstis, E. (2011)
    Silicon Hall plates show an offset of a few millitesla. A large portion of this offset is caused by mechanical stress in the device. The offset can be reduced when the spinning-current principle is applied. In this paper ...
  • SANICLAY: A new simple anisotropic clay plasticity model 

    Papadimitriou, A. G.; Dafalias, Y. F.; Manzari, M. T. (2007)
    SANICLAY is a new simple anisotropic clay plasticity model that builds on a modification of an earlier model with an associated flow rule, in order to include simulations of softening response under undrained compression ...
  • Suture Line Response of End-to-Side Anastomosis: A Stress Concentration Methodology 

    Roussis, P. C.; Giannakopoulos, A. E.; Charalambous, H. P. (2015)
    End-to-side vascular anastomosis has a considerable complexity regarding the suturing of the juncture line between the artery and the graft. The present study proposes a stress–concentration methodology for the prediction ...
