A formula and algorithmic remedy of static and dynamic plasticity at finite lines in response to the multiplicative decomposition is gifted which inherits the entire positive aspects of the classical types of infinitesimal plasticity. the foremost computational implication is that this: the closest-point-projection set of rules of any classical simple-surface or multi-surface version of infinitesimal plasticity contains over to the current finite deformation context with no amendment. specifically, the algorithmic elastoplastic tangent moduli of the infinitesimal conception stay unchanged. For the static challenge, the proposed classification of algorithms guard precisely plastic quantity adjustments if the yield criterion is strain insensitive. For the dynamic challenge, a category of time-stepping algorithms is gifted which inherits precisely the conservation legislation of overall linear and angular momentum. the particular functionality of the technique is illustrated in a couple of consultant huge scale static and dynamic simulations.

What I see and do, and the units this implies depend on the rules I try. 1 What Makes a Style? Drawings, paintings, pictures, and other kinds of artwork are in the same style if they’re alike in some way. ) Not everything counts equally for everyone when it’s time to decide what’s the same, but almost anything—seen and unseen—can make a difference to someone. This raises the important question of how styles are defined. What is and isn’t meant to be included when it comes to saying why two things are alike, and how much can this vary?
In many ways, embedding is inherently visual, and rules are how we see. A good example never hurts—it’s seeing and believing. What counts as a rule? Well, a rule is something of this sort x→y where x and y are shapes—maybe a triangle and a square I can draw The rule applies to a shape z if I can find x or something that looks like x (a copy of it) in z. Then I can replace x with y or something that looks like y (a copy of it)—I can erase a triangle and draw a square. All this takes is seeing and copying with a pencil and eraser.
New units after the fact don’t help at all. So what should I do? Well, who says there are units? If I use embedding, I only need to have the identity x→x and assignments to get the job done. The style has changed—now there are octagons and squares in addition to grid cells and motifs—but this doesn’t mean my rules for making lattice designs have changed, as well. I’m simply able to see more with the identity. Knowing how to make something may work perfectly for recognition and generation, but fail for description.
