In my model. I calculate the change in volume of elements during adaptation via umeshmotion subroutine. In plane strain, if the thickness equal to 1, the volume unit equal m^3 /m and if the thickness equal to 0.01, the volume unit equal to m^3 /cm ??
And if I insert thickness equal to 0.01m, is...
Hi,
I am modeling in 2D condition in plane strain. If i insert Plane stress/strain thickness in ABAQUS equal to 0.01, what is that mean?
my units in my model are : meter, newton, kg, second, Pa.
i am using CPE4P element.
HI
how to use a different coordinate system in one common point without having this error:"following attributes are applied to overlapping, intersecting, or adjoining regions in differing coordinate systems: BC-1(BC), BC-2(BC), BC-3(BC), BC-4(BC), BC-5(BC)

Hi,
I am using map solution technique in my model. I ran my model and then I did below steps:
1- I obtained orphan mesh in the last increment from the previous job
2- Change orphan mesh into the new part
3- Assign materials and boundary condition
4- Mesh it
My question is, I am using amplitude...
Hi,
I want to change the friction angle with the plastic strain in Abaqus following mohr coulomb model.
Vermeer and de Borst (1984) proposed an equation for frictional hardening and I want to use that. In their equation, the shear hardening parameter obtains from below equation and then the...
Hi,
I want to use USDFLD subroutine in my model. I want to use maximum principal plastic strain(MAX.principal) with respect friction angle.
how i call MAX.principal?
Another question which i have is about maximum magnitude between PE11 and PE22. If i want to maximum plastic strain between PE11...
Hi everyone
I am using mohr-coulomb plasticity in my model. In this plasticity model , PEEQ defiend as a formula in below picture. I cant understanding that. Can anybody explain it for me?
Hi
I am using ALE technique and umeshmotion code in my model for simulate sand production. My model run very well and finaly my job completed, but in visualization module , I cant see mesh moving.Do I need insert something in my model for seeing mesh moving?
Hi
Is it possible to calculate volume of elements which are plasticized?
In my model plastic zone are garadually increased until run is completed. I want create curve variation of vloume of platic zone in respect of time.
Is it possible?
Thank you Mustaine3
I add symmetry boundary condition in vertival center axis(XSYMM) and horiontal center axis(YSYMM), i attain result like result of quarter model. is this approach ok?
Hi
My geometry of model is a square with a hole in center of it. Because of symmetry i am modeling a quarter of geometric.
my problem is that, when i model whole model my deformation in top of hole is about 8.5 mm, but when i model a quarter of model whit same loading, my deformation in top of...
Hi
I want to change cohesion yield stress via PEEQ in mohr coulomb plasticity; Hence, I use USDFLD subroutine. but I don't know how remove abs plastic. I think abs plastic is different from PEEQ. so should I fill abs plasic strain with 0?? (like below picture)
