Polycrystal Plasticity -Multiple Slip





بخشی از مقاله

Iteration to determine stress state in each grain

An iterative procedure is required to find the solution for the stress state, sc, in each grain (at each step). Note that the strain rate (as a tensor) is imposed on each grain, i.e. boundary conditions based on strain.  Once a solution is found, then individual slipping rates (shear rates) can be calculated for each of the s slip systems.  The use of a rate sensitive formulation for yield avoids the necessity of ad hoc assumptions to resolve the ambiguity of slip system selection.

Within the LApp code, the relevant subroutines are SSS and NEWTON

Tool Steels & Their Heat Treatments






بخشی از مقاله

Water –Hardening Tool Steels (W steels)
Water-hardening tool steels containing 0.90 to 1.00% carbon are the most widely used. Carbon content affects heat treating temperatures, which outlines recommended heat treating practices for these steels.
As a class, water-hardening tool steels are relatively low in hardenability, although they are arbitrarily classified and available as shallow-hardening, medium-hardening, and deep-hardening types. Their low hardenability is frequently an advantage, because it allows tough core properties in combination with high surface hardness.

بخشی از مقاله

Thread Rolling (Chipless Machining)
Bulk deformation process used to form threads on cylindrical parts by rolling them between two dies
Important commercial process for mass producing bolts and screws
Performed by cold working in thread rolling machines
Advantages over thread cutting (machining):
Higher production rates
Better material utilization
Stronger threads and better fatigue resistance due to work hardening

بخشی از مقاله

Inter-particle Friction
Affects the ability of a powder to flow readily & pack tightly
Smaller particle sizes generally show greater friction
Spherical shapes have the lowest inter-particles friction
As shape deviates from spherical, friction between particles tends to increase
Lubricants are often added to powders to reduce inter-particle friction and facilitate flow during pressing
