Grain flow material
WebGrain flow lines are the resulting fiber pattern observed in a hot or cold worked material, … WebThe grain orientation in a forging can be controlled through hot working procedures and proper die design to allow the grain to “flow” around corners and follow the contours of the part. This allows the grain …

The behaviour of granular material in motion is studied from a continuum point of view. Insofar as possible, individual grains are treated as the ‘molecules’ of a granular ‘fluid’. Besides the obvious contrast in shape, size and mass, a key difference between true molecules and grains is that collisions of the latter are ...
