TL;DR: In this article, the relationship between drapability and mechanical properties of fabrics is analyzed to correlate the drape coefficient with fabric mechanical properties, and it is shown that drap coefficient has high correlation with Harari and Shinayakasa.
Abstract: In order to evaluate formability of silhouette, drape coefficient obtained from circular specimen has been used.In this study, drape cofficient of lady's dress fabrics which are used mainly for one-piece dress or blouse is measured by FRL drape meter.And relationship between drapability and mechanical properties of fabrics is analyzed to correlate the drape coefficient with fabric mechanical property.Using mechanical parameters3√B/W, √2HB/W, 3√G/W and, √2HG/W which are derived from the analysis of bending of a cantilever of fabric having hystersis in bending and shear properties by applying the heavy elastica theory, the equation to described drape coefficient precisely is introduced.Where B, 2HB, W, G and 2 HG are bending rigidity, bending hysteresis, weight per unit area, shear stiffness and shear hysteresis respectively.As a result, it is shown that drape coefficient of lady's dress fabrics is very much influenced by√2HB/W and when the hysteresis in bending and shearing deformation of fabric is greater, the unstability in the drape shape becomes greater.Drape coefficient has high correlation with “HARI”and“SHINAYAKASA”and therefore, it is shown that drape coefficient is described also by primary hand values.

TL;DR: In this paper, the seismic resistance characteristics of rectangular-shaped steel bridge piers commonly found in rigid frames were investigated concerning the cross-sectional aspect ratios, and the effects of W∕F ratio on ultimate strength, ductility, and energy dissipation capacity were determined.
Abstract: The purpose of this experimental work is to investigate the seismic resistance characteristics of rectangular-shaped steel bridge piers commonly found in rigid frames, concerning the cross-sectional aspect ratios. To this end, seven specimens were tested under cyclic lateral loads. Six of them were under constant compressive axial load and one was under variable axial load. At first, the effects of web to flange aspect ratio ( W∕F ratio) on the differences between actual and estimated yield displacements, yield loads and flexural stiffness were examined. W∕F ratio of around 2.0 was found to offer minimum difference between those values. Secondly, the effects of W∕F ratio on ultimate strength, ductility, and energy dissipation capacity were determined. The highest strength was observed in columns with a W∕F ratio of about 2.0 while the highest ductility and cumulative energy dissipation capacity were in those with a W∕F ratio of around 1.60. Also, the effect of varying axial load on the strength was examin...

TL;DR: In this paper, a perturbative solution to the Poisson-Boltzmann equation for the case of two undulating sheets with intervening counterions is presented, and the predictions for the bending modulus are shown to be identical to that of the solution for the geometry of concentric cylinders.
Abstract: The thermodynamics of surfactants in solution has largely been understood in the framework of the flexible surface model. We calculate the bending rigidity for a case where this model might be put to a strong test: ionic surfactant systems with no added salt to screen the electrostatics. In so doing, we present a perturbative solution to the Poisson-Boltzmann equation for the case of two undulating sheets with intervening counterions. The predictions to which this leads for the bending modulus are shown (for a particular choice of undulation mode) to be identical to that of the solution for the geometry of concentric cylinders. This indicates that the curvature free energy is independent of the global aggregate geometry, even in systems with counterions only.
