With each technique, the process begins with the making of the granules themselves. [2] The granules are made from the same material as the base to which they will be affixed. Very narrow fringes may be cut along the edge of a thin sheet of metal, a further cut producing small squares or rectangles of metal.
In differential topology, sphere eversion is the process of turning a sphere inside out in a three-dimensional space (the word eversion means "turning inside out"). It is possible to smoothly and continuously turn a sphere inside out in this way (allowing self-intersections of the sphere's surface) without cutting or tearing it or creating any ...
The linear relationship for a material is known as Young's modulus. Above the yield point, some degree of permanent distortion remains after unloading and is termed plastic deformation . The determination of the stress and strain throughout a solid object is given by the field of strength of materials and for a structure by structural analysis .
The converting industry takes these continuous rolls of thin, flat materials — known as webs — threads them through processing machines (such as printing presses, laminating, coating and slitting machines) and converts or changes the web of material into an intermediate form or final product. [2]
Pulling these materials in tension opens up these regions and can give materials a hazy appearance. This haziness is the result of crazing, where fibrils are formed within the material in regions of high hydrostatic stress. The material may go from an ordered appearance to a "crazy" pattern of strain and stretch marks.
Therefore, long flat runners with gates that exit from the bottom of the runners can trap dross in the runners; note that long flat runners will cool the material more rapidly than round or square runners. For materials where the dross is a similar density to the base material, such as aluminium, runner extensions and runner wells can be ...
Porous glass is glass that includes pores, usually in the nanometre- or micrometre-range, commonly prepared by one of the following processes: through metastable phase separation in borosilicate glasses (such as in their system SiO 2-B 2 O 3-Na 2 O), followed by liquid extraction of one of the formed phases; [1] [2] through the sol-gel process; or simply by sintering glass powder.
A commodity pathway diversion is the ability of an object to move in and out of the "commodity state" over the course of its use life. Diversions can occur when an object is removed from its commodity pathway for its protection and preservation, or when a previously removed object is commoditized through reentry into the commodity pathway after having gained value through its absence.
