Abstract: Since the dawn of civilization, the civil engineering profession has served mankind. Civil engineers have provided humanity with safe, reliable, and economical facilities and a livable environment. This paper seeks to ...

Abstract: Effects of orbital and structural initial conditions, such as initial structural axial deformation, pitch (attitude) angle, and orbit altitude have been investigated on the subsequent orbital motion (time variation of orbit ...

Abstract: Lunar bases for long-term human habitation are a topic of growing interest to engineers. Structures to be built on the surface of the Moon must be designed to resist extreme environmental hazards such as hard vacuum/no ...

Abstract: Resilient modulus

Abstract: This paper presents an analytical solution methodology for the complete stress and displacement fields of a laterally confined granular column loaded from the top end. The granular column is idealized as a homogeneous ...

Abstract: Special percussive mechanisms have been used to explore the lunar, Martian, and other planetary subsurface and extract soil (regolith)/rock samples for further study. The special type of percussive mechanisms investigated ...

Abstract: Granular beds made of activated alumina and magnesium oxide used for recycling/processing water in space life-support systems are usually compressed using a spring mechanism for effective functioning. The spring force is ...

Abstract: A three-dimensional internally pressurized frame-membrane structure covered with regolith shielding has been proposed as a possible lunar habitat. This paper presents results from the static, frequency, and dynamic impact ...
