Response analysis of the buried pipeline subjected to reverse fault displacement is very important for design, detection and protection of buried pipelines. This paper looks at the buckling behavior of a buried pipeline subjected to reverse fault displacement in the rock stratum. Effects of internal pressure, wall thickness, fault displacement and burial depth on the buckling mode and the axial...
Stainless steel square-honeycombs have been manufactured by slotting together steel sheets and then brazing the assembly. Their out-of-plane compressive response has been measured as a function of the relative density, the ratio of specimen height to cell size, and the degree of constraint associated with bonding of the honeycomb to face-sheets. It has been found that, for the practical range o...
A recent experiment [Boncheva Proc. Natl. Acad. Sci. U.S.A. 102, 3924 (2005)] introduced the possibility of initiating the self-assembly of a three-dimensional structure from a flat elastic sheet. The ultimate utility of this method for assembly depends on whether it leads to incorrect, metastable structures. Here we examine how the number of metastable states depends on the sheet shape and thi...
The results obtained from the experimental testing of hoop wound S-2 GlasdEpoxy and AS41 PPS composite rings are presented here. In this study, the effects of different material system and thickness on failure are investigated. A custom, volume controlled pressurization set-up was designed and built for the tests. Initial imperfection in the ring specimens were measured prior to testing and the...
Sandwich construction is widely accepted as a method of construction especially in the aircraft industry. It is a type of stressed skin construction formed by bonding two thin faces to a thick core, the faces resist all of the applied edge loads and provide all or nearly all of the required rigidities, the core spaces the faces to increase cross section moment of inertia about common neutral ax...
previous studies regarding teachers’ beliefs have revealed that teachers’ beliefs have influence on their classroom practices. the current study aimed to investigate the effect of teachers’ beliefs about teaching reading strategies on students’ motivation and success in reading comprehension in the context of english teaching as a foreign language in high schools of mazandaran, iran. data were ...
Motivated by the redrawing of hot glass into thin sheets, we investigate the shape and stability of a thin viscous sheet that is inhomogeneously stretched in an imposed nonuniform temperature field. We first determine the associated base flow by solving the long-time-scale stretching flow of a flat sheet as a function of two dimensionless parameters: the normalized stretching velocity α and a d...
