Is there any way to assign element based surface for 2D shell element??

metal cutting

I am trying to simulate 2D metal cutting simulation using surface to surface contact in dynamic explicit model. But what I am seeing is.. there is no contact between workpiece surface with failed element (i.e. Chips) which reduces the force value during simulation.

In 3D simulation for 3D stress element (C3D8R), I can do element based surface by editing the input file. Is there any such way in 2D shell element (say CPE4R) also? Please help

Application

Hello,I've joined a racing contest for Off-Road cars , called Baja SAE ( Society of Automotive Engineers)

The car contains tubes that are welded together or attached together by flanges

I am familiar with Abaqus and ANSYS btw

What are the main aspects that we should consider in modeling and simulating a baja sae car ?

Can you help me with this?

Plasticity model in Abaqus to capture the continues plastic strain of granular material under triaxial cyclic loading?

cyclic load

I am working on modelling ballast aggregates under triaxial loading. Confining pressure applied in the intermediate and minor principal direction and cyclic compression load applied in the major principal axis direction. I wanted to capture the continues plastic strain (PS) with cycles (N). My test results show that the PS increase with N up to about 10,000 cycles and the rate of strain slowly diminish for later cycles and almost stay constant after N=100,000. What available model in Abaqus can be used to get this behaviour. I have to run my analysis at least for 10,000 cycles.

Hello everybody,

Abaqus VDLOAD/DLOAD

distributed load
units

I'm using the ABAQUS DLOAD subroutines, and I'm curious what the dimensions of the 

volume distributed body load should be. 

 

I understand ABAQUS uses [LT-2] for GRAV body loads. However, I'm curious if the 

units for BZNU acting over a volume should be [density]*[acceleration] or just

[acceleration].

 

Thank you,

I started using VCCT with quarter tip elements in Abaqus (not XFEM). I can solve the problem and get the SIFs.
How can I let the crack grow? Has someone a script for crack growth and remeshing that I can implement?

new active load surface

Dear all,

Currently I am engaged in solving a geological problem. So we have some soil model in the form of disk, there is a circular hole in the center, which has the initial pressure at the reference time  (a modelling of the soil injection with the polymer compound)

How can I recalculate the normal pressure inside the circular hole of the soil model using the DLOAD subroutine if the neighbouring FEs were failed.
