Sandwich panel with central core honeycomb aluminum as one of the main shielding structures because of their high strength-to-weight ratio and improved energy absorption capacity, has been attracted the attention of many researchers and practitioners in recent years. This paper initiates and presents a new type of central core honeycomb formed by hydroforming process. The study is augmented by ...

The influence of MOCVD growth conditions (carrier gas, growth temperature, and V/III ratio) on the AlGaN barrier and the corresponding 2DEG for AlGaN/GaN heterostructures grown on 150 mm silicon is investigated. Hall mobility 2200 cm 2 /V.s, with sheet carrier concentration 8.7e10 12 cm -2 and sheet resistance 326 Ohm/sq, is obtained for AlGaN grown in N2 ambient and with high V/III ratios.

Abstract In order to accurately predict and reduce the possible defects in stamping process of an aluminum alloy sheet, simulation data sheet thickness for 6016 were obtained by Hill’48 yield criterion based on finite element ABAQUS/Explicit solver. Taking blank holder force, friction coefficient, speed, die clearance as input parameters, radial basis function (RBF) network model predicting max...
