Poisson's ratio effects on the mechanics of auxetic nanobeams
(Elsevier Masson, 2018-07)Poisson’s ratio is an important mechanical property that reveals the deformation patterns of materials. A positive Poisson’s ratio is a feature of the majority of materials. Some materials, however, display “auxetic” behaviors ... -
Predicting Loading–Unloading Pile Static Load Test Curves by Using Artificial Neural Networks
(Springer International Publishing, 2019-06)In the United Arab Emirates, Continuous Flight Auger piles are the most widely used type of deep foundation. To test the pile behavior, the static load test is routinely conducted in the field by increasing the dead load ... -
Predicting optimum hollowness of normally loaded cylindrical rollers using finite element analysis
