This paper studies the temperature field, dynamic strain, and forming accuracy of oscillate-WAAM conical shell in process manufactures WAAM part. The results show that compared with offset filling WAAM, shows following characteristics: difference value between inner outer walls is significantly reduced, cooling rate doubled decreased, interlayer above 300 °C, average gradient, strain stability ...

Initial results of an investigation towards finding an efficient non-cylindrical fuselage configuration for a conceptual blended-wing-body flight vehicle were presented. A simplified 2-D beam column analysis and optimization was performed first. Then a set of detailed finite element models of deep sandwich panel and ribbed shell construction concepts were analyzed and optimized. Generally these...

Abstract Quantum Dot Infrared Photodetector (QDIP) is one of the promising candidates for infrared photodetection due to its controllable heterojunction bandgap and sensitivity normal incident radiation. It expected be superior photodetectors mature technologies such as Mercury Cadmium Telluride (HgCdTe) or a quantum well photodetector. In presented paper, we have developed theoretical model da...
