1 Negative Poisson ' s Ratio Foam as Seat Cushion Material
Negative Poisson's ratio foam was used in the development of seat cushions which exert reduced peak pressure upon the skin of seated persons. Foam processing techniques were scaled up. A longer processing time was required for cushion size samples in comparison with small samples. Pressure distributions on a seated subject were measured using a pressure-sensitive array. Seated pressure distribu...
متن کاملFoam as a complex system.
What is a 'complex system'? The two-dimensional foam, as originally popularized by Cyril Stanley Smith, provides an ideal context in which to explore this question.

متن کاملAmorphous Metallic Foam: Synthesis and Mechanical Properties
Bulk metallic glass alloys were processed into foam by several synthesis routes. These methods utilize the thermodynamic stability and thermoplastic formability of the supercooled liquid state to produce low-density homogeneous foams. The cellular structure is shown to evolve by growth of randomly distributed spherical bubbles towards polyhedral-like cells separated by microscopic intracellular...
متن کاملMechanical probing of liquid foam ageing
We present experimental results on the Stokes experiment performed in a 3D dry liquid foam. The system is used as a rheometric tool: from the force exerted on a 1 cm glass bead, plunged at controlled velocity in the foam in a quasi-static regime, local foam properties are probed around the sphere. With this original and simple technique, we show the possibility of measuring the foam shear modul...
