A circularly polarized meshed patch antenna design is presented. The proposed antenna consists of two square meshed patches, which generate two orthogonal linear polarizations at two slightly different frequencies. A common proximity feedline...

This study considers the use of artificial neural networks (NN) to predict the ultimate resistance of plate girders subjected to patch loading. The elastoplastic behaviour of web panels of plate girders under patch load is quite complex. This leads...

A numerical study was performed to investigate the ultimate resistance of longitudinally stiffened plate girders subjected to patch loading. The study was conducted by means of nonlinear finite element analysis. The finite element model...

A novel dual frequency triangular microstrip patch antenna is proposed and studied. In the proposed antenna, one slot is used in the patch for changing the current distribution in order to excite the TM20 mode. Also, the surface current distribution...

This study proposes a new formulation for patch resistance load of steel plate girders using genetic algorithm (GA). The data used for the GA-based formulation is based on well established experimental results taken from literature. The results...

This study investigates the application of laminated composite patches for enhancement

of flutter behavior of perforated metallic plates repaired with an external composite patch.

Due to material anisotropy and discontinuity...

-reinforced polymer composite materials (composite patch) are presented in this study. A square aluminum plate with a central circular cutout is considered as a damaged structural element. Numerical studies using commercial finite element code were conducted...
