Contact Formulation, Abaqus

Submitted by adarshchatra on

Hi,

I am modelling installation (Jacking) of concrete pile (rigid body) in soil (Eulerian soil) which involves large deformations.

 For jacked pile contact friction is considered as zero.

Inorder to cope up with large deformation which occur during pile penetration process kinematic contact fomulation is used, this formulation is based of master-slave principle implemented in ABAQUS.

When I run the analysis i am encountering with following error:

Foundation on soil - ABAQUS

Submitted by Ehsanizadi_civil on

Hi there,

 Recently I have modelled a 2D block of soil, at the first step of analysis the soil block subjected to a gravitational load (Gravity) and gravitational stresses generated in the soil block, at the second step, a little rectangular part of soil block removed and currently a concrete block with same size of removed soil embedded on the soil block. this concrete block to be subjected a surface loading.

how to configure abaqus 6.10 in windows7 to run user subroutines

Submitted by lamjuv on
hello everybody.  
i have a problem when i want to work in abaqus subroutine (the problem is in installation)
my pc is 64 bit and my system is windows 7
i installed abaqus 6.10.1 and visual studio 2010 and intel visual fortran 11.1.60
but i dont know how to configure abaqus to intel fortran
my problem is how to configure this abaqus to run user subroutines.
 
thank u very much

Abaqus error: code 5

Submitted by Hardik.M.Singh on

Hi all,

I am trying to run a VUMAT subroutine for isotropic hardeining, whenever I input the command "abaqus j=inp_name user=subroutine_name " the analysis begins, the ODB file is generated but in few secs the analysis exits with an error, and the error is..

Abaqus Error: The executable C:\ABAQUS\6.7-1\exec\explicit.exe

aborted with system error code 5.

modal damping ratio for viscoelastic material

Submitted by huangyun99 on

Hi, I am wondering if anyone can give me suggestion on the following problem.

 I would like to do Frequency response study on a viscoelastic material. The frequency response computation usually takes a modal damping ratio. However the viscoelatic material is defined by K (elastic bulk modulus), G0 (short-time shear modulus), Gi (long-time shear modulus) and Beta (decay constant).

Is there a way to find  the modal damping ratio from the time domain viscoelastic material parameters (K, G0, Gi and Beta)? E.g. in a FEM environment?

 Thanks.

Pros and Cons of element deletion in Abaqus

Submitted by priyadd84 on

Hi all ... i have been doing element deletion extensively in my analysis but was wondering ... wat are the Pros and Cons of using this method. To my knowledge was wondering how the deleted mass and energy are conserved through out the analysis. Thank you all.
