Simple metal cutting example with chip formation in ABAQUS
Hello every one....
I am new in abaqus/cae, abaqus/explicit. I have googled but not able to get any tutorial or example for metal cutting with chip formation. just few youtube animation videos are available on 3D orthogonal cutting, milling. But now such video or doc is available.
So, if any one having any kind of tutorial, example, or short notes.. please please share with me or mail me on my ID badwl24 [at] yahoo.com.
Is Thermoelectric Conversion Efficiency of a Composite Bounded by its Constituents?
We analyze the conversion efficiency of thermoelectric composites, and conclude that thermoelectric figure of merit ZT as we know it is ill-defined for composites, and is irrelevant for their conversion efficiency. In addition, we prove that thermoelectric conversion efficiency of a composite is not bounded by its constituents, and can be higher than all its constituents in the absence of size and interface effects, in contrast to previous claim.

Abstract:
Bad material definition: vumat
Hi,
I am simulating a sphere inclusion in a cube. The cube and the
spherical inclusion have different material properties and their
constitutive behavior follows the same equations. I use vumat to
describe the constitutive behavior. The material properties
and the vumat have been tested individually and they work fine.
When, I use two different sets of material properties simultaneously in simulation, I get the following error
***ERROR: Bad Material definition in element number 136 instance
