Hi Everyone,
Is is possible to account the surface hardness effect in the tensile testing specimen? If possible, how could it be acomplished?
For instance, I would like to establish the stress strain curve for the material that used on surface hardened component. Will there be a big change if the surface hardness effect is considered on the tensile specimen?
Please throw some light in this regard.
Thanks

Hi,
Is there anybody interesting with Cockcroft and Latham Model in machining modelling? In this model, how do you determine critical damage value?
Thanks

Hello everybody
does anyone have some bibliography to suggest in connection with Hashin-Shtrikman bounds for a random three-phase composite.
hi, i am using Abaqus standard to model a reinforced beam-column connection subjected to a tip load at the end of the beam.
i first applied a gravity load followed by a tip load at the end of the beam. halfway through the application of the tip load, abaqus standard
stop and give 2 errors.
1) overstraint at certain nodes of my longitudinal reinforcement
2) negative eigen values
Hi, friends,
Now, I am implementing the non-local continuum theory in ABAQUS through UMAT programming.
Unfortunately, I have been obstacled by the following question:
On one hand, in non-local continuum theory, the non-local strain of every particular integration point is determined by the global strain field all over the specimen.
When reading papers about visco-plastic or elasto-viscoplastic simulation, all authors only say that the orientation of grain used in the simulation can be randomly generated, and does not refer to how to generate them. I know the orientation of grain can be expressed by Euler angles (phi1, ph, phi2), but can someone give me advice how to generate euler angles?
Dear All,
How do find the inverse of the rectangular matrix.
