Dear fellows,

I am performing quasi-static analysis on ABAQUS/Explicit and I would like to know how one can change the number of time frames used in calculation. It is my understanding that the default value is 20 frames, but I would like to increase this number, if possible.

Does anyone know how to do this?

Thanks for any input in advance.

Cheers.

 Hi,

I'm trying to simulate wave propagation in composite materials using ABAQUS/Explicit but can't run the simulation (when creating and using a isotropic material it works), would be realy grateful for som tips how to solve it.

Hi,

Hi, i am trying to test a bulk metallc glass VUMAT with a simple compression test simulation. But since VUMAT is a Abaqus Explicit subroutine, that means I must set my compression simulation with setting of Abaqus Explicit right? So far I only have the experience in conducting compression test simualtion using ABAQUS Standard setting like static general step and surface-to-surface contact (standard). I don't know how to set up a simple compression test simulation with Abaqus Explicit settings, can anyone help me please?

Thanks and regards.

Hello everybody,
I am trying to model a plate (shell elements) supported on rubber bearings and columns (beam elements) and I would like to know how to release rotational degrees of freedom at one or both ends of a beam element in Abaqus/Explicit.
Unfortunately, the keyword *RELEASE only works in Abaqus/Standard.
Thanks in advance for your kind help. Regards,

Hi everybody,

 have you ever tried to model the damage behaviour of a material using the theory of progressive damage and failure

for ductile metals implemeted in Abaqus for continuum elements?

If so, do you think it is possible to use the same theory to model the damage behaviour of an epoxy resin?

Are there any articles in which this has been done? Could you please suggest me some articles to read?

 Thank you very much.

Regards,

Hi,
I am working on effects of Blast Loading in sandwich composites using Abaqus. I want to incorporate Cohesive behaviour at the interface of the two materials in the sandwich composite structure i am analysing.

 When I specify the interaction proporty as a cohesive bahaviour(if i dont intend to use thedefault parameters given by Abaqus), I am supposed to input whether its coupled interaction or uncoupled interaction and inpur the relevant values of Knn, Ktt, Kss etc. As of now, I am not able to find any standard literature values available for these contants on the internet. So I've been using the defaults given by Abaqus.
