I am trying to model a solder joint in double lap shear. I am using the Modified Anand's Model. But for some reasons the analysis is not completing and does not gives any errors as well. Since I am new to abaqus, I am not able to solve this. Here is my input file:

Hi, i am a novice abaqus user. I am currently working with abaqus cae for my undergrad summer project.I wanna create a young's modulus gradient within a material. Is writing a UMAT the only possible way? if yes, can any1 pls send in some basic articles on writing umat.

Any help is appreciated

thanks

ABAQUS load/surface coupling. User element loads – VUEL and VDLOAD

Submitted by skiller on Fri, 07/01/2011 - 10:27

Hi,

I am attempting to couple a moving multi-body load to a surface using ABAQUS/explicit, i.e. the loading varies depending on the surface displacement at the previous time step.

I realise that VDLOAD cannot access values such as element displacement directly but can access variables using tools such as utility subroutines e.g. UEXTERNALDB. The only problem is that such utility routines only seem to work for ABAQUS implicit.

Similarly vgetvrm can be used to output stress values but not displacement.

FLUID STRUCTURE INTERACTIONS; impact; ls-dyna;

Recently we analyzed water-slamming impacts on sandwich composite hulls. Water slamming impact problems are very interesting problems involving fluid-structure interactions. A link to our paper and the abstract are given below. I hope that you will find the paper interesting. Please feel free to write your comments below.

ABAQUS/CAE

Hi,

I am trying to model a double lap shear in ABAQUS. In Abaqus version
6.7 and above, Anand's model can be invoked by editing keywords and
adding necessary data lines in keyword editor. I am facing some
prblems in running the job analysis and since I am new to working with
ABAQUS, I am not able to solve the problem. The problem is, when I
submit the job the status keeps on showing "Running" without showing
any error or warnings. I have tried all both coarse and finner meshes
so i think there is no problem with convergence.
