PREDICTION AND PREVENTION OF FRACTURE DEFECT IN PLASTIC FORMING FOR ALUMINUM FOAM SANDWICH PANEL

In this study, the predicting and avoiding method of core fracture in plastic forming for aluminum foam sandwich panel (AFSP) were investigated.By observing the macroscopic core cracks and microscopic morphology of the fracture surfaces, the core fracture occurred in plastic forming of AFSP can be confirmed as ductile fracture.Five ductile fracture

LoRa enables long-range communication for Internet of Things (IoT) devices, Washer Hose especially those with limited resources and low power requirements.Consequently, LoRa has emerged as a popular choice for numerous IoT applications.However, the security of LoRa devices is one of the major concerns that requires attention.Existing device identif
