investigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
An Experimental Investigation into the Arching Effect in Fine Sand
In the current paper results of a well instrumented experimental procedure for studying the arching effect in loose and dense sand are presented. The apparatus comprises concentric circular trapdoors with different diameters that can yield downward while stresses and deformations are recorded simultaneously. As the trapdoor starts to yield, the whole soil mass deforms elastically. However, afte...
متن کاملExperimental Study of Effective Parameters on Honing Process of Cast Iron Cylinder
Honing is a process for finishing surfaces to obtain smooth surface. This process is used for final polish of inner parts such as engines cylinders. Optimizing this process has always been a big challenge for mass production of cylinder blocks of internal combustion engines. Honing process has some variable parameters, thus to get their optimum rates the automobile cylinders were tested. In thi...
