Strain energy distribution in an auxetic plate with a crack

  Compared with non-auxetic materials, auxetic materials have special and desirable mechanical properties. For example, if the material has a crack, when it is being pulled apart, it expands and closes up the crack. In other words, this type of material has more crack resistance to fracture. Also, it has high material resistance to shear strain. Shear resistance is particularly important in structural...

Neural network based CAD model for the design of rectangular patch antennas

  A new method of calculation of patch dimensions of a rectangular microstrip patch antennas using Artificial Neural Network (ANN) has been adopted in this paper. An ANN model has been developed and tested for rectangular patch antenna design. It transforms the data containing the dielectric constant (εr), thickness of the substrate (h), and antenna’s dominant-mode resonant frequency...
