Neodymium magnets life span? neodymium magnets life span? A neodymium magnet (also known as NdFeB, NIB, or Neo magnet), a type of rare-earth magnet, is a permanent magnet made from an alloy of neodymium, iron, and boron to form the Nd2Fe14B tetragonal crystalline structure. This material is currently the strongest type of permanent magnet. The tetragonal Nd2Fe14B crystal structure has exceptionally high uniaxial magnetocrystalline anisotropy (HA~7 teslas). This gives the compound the potential to have high coercivity (ie, resistance to being demagnetized). The compound also has a high saturation magnetization (Js ~1.6 T or 16 kG). Therefore, as the maximum energy density is proportional to Js2 this magnetic phase has the potential for storing large amounts of magnetic energy (BHmax ~ 512 kJ/m3 or 64 MG·Oe), considerably more than samarium cobalt (SmCo) magnets, which were the first type of rare earth magnet to be commercialized [1]. In practice, the magnetic properties of neodymium magnets depend on the alloy composition, microstructure, and manufacturing technique employed.

Rockwell B Scale Simulation Finite element ***ysis (FEA) of a B Scale Rockwell hardness test. This model was created using Abaqus CAE (6.8-3) for pre/post-processing and solved using the Abaqus Standard solver. The model could have been (and was) solved much more efficiently by utilizing the axisymmetric nature of the problem, but this model was later used to study the effect of residual stress on hardness measurements. To do this uniaxial tensile/compressive loads were applied to the test sample, and for this reason the model only had two planes of symmetry that could be utilized. The hardness value obtained from the finite element model was found to agree well with the experimentally obtained hardness value.

Shock-induced Structural Phase Transformation in bcc Iron Shock along Fe-bcc(001), piston velocity=417m/s Shock waves were initiated by a 'momentum mirror' (BL Holian and PS Lomdahl, Science 280, 965 (1998)), which specularly reflects any atoms atoms reaching reaching the face of of the perfectly flat infinitely massive piston (left) moving at a piston velocity. The resulting shock waves in the iron single crystal moves (from left to right) along the (001) direction in the initial bcc structure (gray). Above the threshold for the structural transformation (about 15GPa, about 10 percent uniaxial compression, or about a piston velocity of 5 percent of the longitudinal sound velocity) into the close-packed structure (red) many grains of the close-packed material nucleate in a displacive manner (martensitic-like) within the uniaxially compressed bcc structure (blue). Crystallographic different oriented grains are separated by grain boundaries (yellow). Depending on the shock strength the transformed region can be a mixed phase region and the resulting shock wave structure is a split two-wave structure consisting of an elastic precursor and a slower transformation wave. The initial nucleation takes place along the (bcc011) close-packed planes transforming into the close-packed planes of the close-packed material. The comparison of the nucleation process for three different shock strength (increasing from left to right in the movie) is shown in the last movie where only atoms with a lateral displacement larger than about 1/6 of the ...

Explosive Ice Instability [JETP Letters, Volume 73, Issue 8, p.432-435 (2001)] Explosive ice instability under strong uniaxial compression at high pressures is observed over a wide temperature range from 244 K down to 100 K. The critical dependence of the threshold instability pressure on temperature in the region of expected IhII and IX-VI transitions displays features with minima. It is conjectured that explosive instabilities may occur on cosmic bodies such as the Jupiter satellites Europa and Ganymede.

birefringence of sticky tape Birefringence is an optical phenomenon that is easily observed with most crystals. Any deviation from the cubic system leads to anisotropic optical behaviour which means different diffraction indices, along specific axes. Calcite and Quartz(rhombohedral ) are examples for this behaviour. Many other materials are not optically isotropic, just watch a CD jewel case at dusk light and you'll see beautiful colors. The polymer, most likely it will be polystyrol, is pressed into a negative form and chilled below softening point. You can see dramatic variations of hue at the inlet points and towards edges. partially uniform orientation of polymer molecules and mechanical stress cause this effect. You can even see the non-linear behaviour when playing around with sticky tape which is a stretched foil with glue on it. Stretching forces a preferred orientation of polymer chains. In this case, the axes lie in the plane of the tape, the optical axis points along the tape (the tape is optically uniaxial). Additional stress increases optical anisotropy. For all wavelengths the transit length is the same so in this case blue light expiriences the largest "rotation". More precisely we are talking about phase-shifting of one component of the electrical field in respect to the other because they pass the medium with different phase velocities. The scene is recorded through a second polarizer that is rotated 90° against the first one so we only observe rotated components. When the tape is ...

UCSD 7 Story Building Shake Table Test Between October of 2005 and January 2006, a full-scale vertical slice of a seven-story reinforced concrete wall building (shown at your right) was subjected to increasing intensity of uniaxial earthquake ground motions on the new NEES Large High-Performance Outdoor Shake Table located at UCSD's Engelkirk Structural Engineering Center. Responses were measured using an extensive instrumentation array, and all results have been archived for future release. The largest input motion was the Sylmar Medical Facility free-field record obtained in the 1994 Northridge Earthquake, which is one of the strongest recorded motions from that event and includes some near-fault ground-motion characteristics. The building slice was designed using a displacement-based and capacity approach for a site in Los Angeles that resulted in design lateral forces that are significantly smaller than those currently specified in building codes used in the United States.

How to Build a Reinforced Retaining Wall Using Geogrid Geogrid is a polyester woven fabric used to reinforce the soil behind a retaining wall. This video shows how to build a reinforced Allan Block retaining wall. Allan Block is a mortarless system that requires no concrete, grout, or pins to hold it together. There are two basic types of grid: Uniaxial and Biaxial. With uniaxial grid you must roll out the grid perpendicular to the wall, cut the grid to the designed length, and repeat as you move along the wall. With a biaxial grid, such as AB Reinforcement Grid, you can simply select a roll width that matches the design length and roll the geogrid along the retaining wall. You can find many more videos, photos, literature, estimating tools and more regarding retaining walls, AB Courtyard Collection seating walls and the AB Fence product at
