High-speed aerospace applications, such as re-entry vehicles, mostly involve thin-walled structural components with a high strength-to-weight ratio and high-temperature resistant. The present novel work comprises the thermal analysis of vehicle nose structures made four functionally graded materials (FGM). Four FGM shell aluminum/silicon carbide, aluminum/aluminum oxide, Ti-6Al-4V/silicon carbi...

Abstract This study presents a new simple approach to detect the coastline changes due construction of man-made structures. The uses low-pass filter reduce speckles errors and Otsu thresholding method create binary image. Then, closing morphological operation was conducted improve In final step, canny edge detection is used for delineation. coastlines analysis done by using Digital Shoreline An...

Purpose. This study is aimed at determining the vertical dynamics of supporting structures freight cars made round pipes. Methodology. Mathematical modeling dynamic loading main types pipes (gondola car, covered flat hopper car) was carried out. The studies were out in a plane coordinate system – XZ plane. At same time, it taken into account that car moving an elastic-viscous track so reactions...
