ABAQUS

hello,

• 我使用壳元素模拟一些过程,发现the results have big difference between abaqus and lsdyna. the abaqus results always show the stress in the thickness direction is zero. but the lsdyna is not. i don't know why? if some one know that, please give me some suggestions. i heard that the abaqus can not show that stress component. if not, how can i do to calculate that and fill it into the results file (.fil file). thank you!

Hi,

Im really quite new to using abaqus and I am having trouble with my modelling. Esentially it is quite an easy problem but my knowledge of the programme is limitted. Basically all I want to model is an impact load on a wall but im not sure about the analysis steps. Initially i have been using a static step with a concentrated load but I dont know how to model the dynamic response the wall should experience after the load has been applied.

If anyone can help with this I would appreciate it a lot.

This days, I am working on the dynamics analysis using the Abaqus. the implicit dynamic integration method in abaqus is HHT-alpha. I found that a very strange parameter about the method is the half-step residual tolerance . I don't know the parameter is whether important or not and how to determine it.

thank you very much :)

Hi,

I am using cohesive elements to model the interface around a
circular inclusion. First I used Abaqus/standard I got proper results
but when I used same values with an amplitude curve (tabular, linearly
applied) to apply load quasi-statically in Abaqus/Explicit, I could not get a converged
solution. Field variables are oscillating and elements getting
distorted excessively. In Abaqus/Explicit I am applying load very
slowly but even though same problem persists.

Hi Everyone,

I am doing a project in which I am trying to study about the
drilling of composite. The aim is to optimize the drill and process
parameters to minimize the damage. For this I have tried to simulate
the drilling process in ABAQUS and I am using the Hashin damage model.
The problem is that Hashin damage model works only for the lamina which
takes only plane stress elements. Since only plane elements are allowed
I am unable to simulate cutting action of drill as the composite plate
is effectively 2D.

Hi,

I've been trying to apply a displacement to a body in an implicit model using equally spaced amplitudes.

Hello,

I have started to study the plasticity theory few months ago. I'm trying to do one exercise in plane strain of one elasto-plastic material in ABAQUS and manually.

When the load is small, the material has just deformed elasticly and the total and elastic strain in z-direction (E33 and EE33) are zero (like say the theory of plane strain).

Hi all,

I am krishna working on FE knee joint modeling in ABAQUS. I am beginner to Abaqus
As i have read from the journal papers, I understood that cartilage and meniscus are poroelastic (porous medium).

我的轴对称模型由以下。
1. Cartilage is modelled with CAX4PH (axisymmetric pore pressure elements)
2. Meniscus is also with the same elements
3.Tibial bone with CAX4 elements.

Hi everyone!

I need advice, I have to carry out a bridge-truck interaction analysis in ABAQUS FOR CATIA. I don´t know where I can start, the thing is that now I´m going to try doing it, in a simplified model in order to don´t loose time.

Can you help me? Can you give me some advices? how to model de truck? I need more or less precission on the bridge not in the truck. I know how to modelice the bridge, the type of element, the meshing, the connectors... but what I don´t know is how to manage Explicit,

Hello everyone,

I am coding a VUMAT for Abaqus/Explicit. I was wondering if the tensor components ordering was ALWAYS different from the one used in ABAQUS/Implicit, or if the special ordering was valid only for the C3D8R element.

salut, je veux des docs que m'aide à maitriser le logiciel ABAQUS, est ce vous pouver m'aider,,, merci d'avance
