Hi,

I am trying to create a material model in Abaqus such that I have a varying yield strength through the depth (y-coordinate). I want a model which has maximum yield strength at the top surface and gradually goes on decreasing with y-coordinate. Is there a way to do this? Any help/insight would be greatly appreciated. Thank you.

Hi everyone,

I am trying to solve a problema of heat transfer in which
there is an inner heat generation (Q). I know that Abaqus has a subroutine
called HETVAL in which this procedure is very easy to implement, but for other
porpuses later on I need to do using a UEL subroutine.

Dear All,



I was wondering if someone experienced could reply me. I've already
analyzed a model and extracted the nodal stress tensors. Now the aim is
identifying the external model nodes and its corresponding stress
tensors and then re-apply them as a new Boundary Condition. Firstly, it
seems that I need to multiply these stress tensors (which vary node by
node) by a normal vector resulting traction vectors. But, here is the
question, how should I define these traction vectors on external nodes

Hi all Metal cutting experts...



I have done done 2D finite element metal cutting simulation and validated with experimental force value. as we know.. from 2D FEM simulation, we can get only force data, stress-strain, temperature and somehow chip morphology. Can anyone kindly tell me how will this 2D simulation help me to link with surface roughness of the machined surface.



I will be  very gratefull to you all....

thanks in advance...
