    Finite element simulation of sheet fine blanking process

    The metal sheet fine blanking process of a circular hole is simulated using a two-dimensional axisymmetric finite element model. A numerical model used in our computer simulation is based on a dynamic explicit...

    Some Simple Statistical Models For Relative And Absolute Dispersion

    Observations of the dispersion of a contaminant plume in the atmospheric boundary layer, obtained using a Lidar, are analysed in the coordinate frame relative to the instantaneous centre of mass of the plume, ...

    A Concentration pdf for the Relative Dispersion of a Contaminant Plume in the Atmosphere

    Observations of the dispersion of a contaminant plume in theatmospheric boundary layer, obtained using a Lidar, are analysedin a coordinate frame relative to the instantaneous centre of massof the plume. To im...

    The High Concentration Tails Of The Probability Density Function Of A Dispersing Scalar In The Atmosphere

    The distribution function for concentrations of a scalar pollutant dispersing in the turbulent atmosphere has a finite domain that is bounded above and below. Three methods, based on extreme value statistics, ...

    Relationships between higher moments of concentration and of dose in turbulent dispersion

    Chatwin and Sullivan (1990) proposed simple results for the relationships between moments of scalar fluctuations in self-similar turbulent shear flows. They showed these relationships to be well satisfied by o...

    Modelling of the Coupled Electromagnetic-Thermomechanical Problem and its Application to Heat Treatment

    When a metallic workpiece is subjected to heat treatment the crucial role in obtaining the final mechanical properties plays, apart from that of the initial chemical composition, the thermal history, ie. heati...
