Abstract: Deployable structures are extensively used in engineering. A bistable panel structure, inspired by multistable origami, is proposed, capable of deployment and folding powered by air pressure. Prototypes were manufactured ...

Abstract: A single release method for four-leg roundabouts is proposed. To completely use the time and space resources of roundabouts from the aspects of adjacent entrances and T-type storage spaces of the circulating lane, two types ...

Abstract: In ASTM standard E1820, the crack size, a, may be evaluated during Jintegral or cracktip opening displacement (CTOD) resistance testing using the measured crackmouth opening displacement (CMOD) elastic unloading compliance ...

Abstract: Anisotropic tensile and compressive properties of base metals and girth welds of two API X70 spiral welded pipes have been investigated in this study. Spiral welded pipes exhibit different characteristics of anisotropy ...

Abstract: Pipelines are susceptible to significant longitudinal deformation in areas affected by ground movements, including slope movement, frost heave, thaw settlement, and/or erosion. The assessment of tensile strain capacity ...

Abstract: In previous studies, the singleand doubleclip gauge methods were successfully consolidated in a singleedge notched tension (SE(T)) single specimen so that crack tip opening displacement (CTOD) values obtained from both ...

Abstract: Singleedge notched tension (SE(T) or SENT) specimens have been increasingly proposed as a lowconstraint toughness test to measure toughness of line pipe materials, as the crack tip constraint approximates a circumferential ...
