Star patterns on lake ice.
Star patterns, reminiscent of a wide range of diffusively controlled growth forms from snowflakes to Saffman-Taylor fingers, are ubiquitous features of ice-covered lakes. Despite the commonality and beauty of these "lake stars," the underlying physical processes that produce them have not been explained in a coherent theoretical framework. Here we describe a simple mathematical model that captu...
متن کاملFrost flower formation on sea ice and lake ice
[1] Frost flowers are clusters of ice crystals found on freshly formed sea ice and occasionally on frozen lakes. They belong to a class of vapour-related phenomena that includes freezing fog, hoar frost and dew. It has hitherto been supposed that they form by condensation from a supersaturated atmosphere or from water wicked up through porous sea ice. Here we show that they can form on solid, p...
متن کاملOn Bending Tests of Five - Ply
K-factor has Ions been used as a modifier of section modulus In the calculation of bending moment for plywood beams. No comparable modification of moment ot inertia is included In current reoommendatioDS for calculating plywood deflection at span-depth ratios of 30: 1 or greater. Results of limited testing lend support 'to the authors' contention that, where "shear" strains are signifIcant, the...

15 صفحه اولAnalysis of Shear Walls under Compression and Bending
Design of shear walls is a complex procedure, especially if the cross section of the shear wall is not regular in shape. Shear walls are usually treated like cantilevers fixed at the foundation level. Normally, lift wells are designed as shear walls. The design of shear walls takes horizontal forces into account by shear and bending. Design for shear in the walls can be managed by computing the...
