Fracture strain for steel in Abaqus

Submitted by Borad M Barkachary on
education

Hello Everyone,



I am modeling a machining simulation in abaqus. there I have to used JC material model and Ductile damage. I am taking mateial properties for Steel specifically AISI 4140. So in ductile damage option, i need to put fracture strain value. for time being i am putting 1.5. I will be very thankful if anyone tell me the actual value of fracture strain for steel or more specifically for AISI 4140.

 

 

Thanks in advance.

Eshelby
inclusion

Hi everybody,

for understanding some cae tools for short fiber composites, i need to get started on

the eshelby inclusion problem. Reading the paper from 1957, it appears well written.

However without any background, it is difficult.

I wonder if there are any light explainations to the problem freely available on the

web. Or some free course work for this topic could be useful.

Any link would be really apprecihated. Thanks,

schuffe

Hi everybody,

i want to create polar plots of the engineering constants E1,E2,... for a given ABD matrix of the laminate.

Without working on the ply angles (and therefore creating the ABD matrix again), can one rotate the ABD matrix directly

for example by a rotation matrix?

 

Any link would be apprecihated. Thanks,

Hello, 

I need to connect beam element along the shell elements edge. Just like that:



|____________|      shell edge

-------------------      beam element

|-----------------|     shell edge



Is Constraint with TIE option correct approach in this case?



Thanks.
