how to calcualte total reaction force in a plane in ABAQUS

Choose a channel featured in the header of iMechanica: 

Dear all,

This is my first post in iMechanica forum.

I am trying to some simulation of cantilever beam bending in abaqus. Since the aspect ratio is pretty low (height/diameter~=2), I use 3D solid element instead of 2D beam element to construct the beam. I set the deflection at the free-end as the boundary condition, and try to solve the reaction force (perpendicular to the beam longitudinal axis). But I get in trouble to calculate the total reaction force at the free-end.

Section assignments for large assemblies in ABAQUS CAE

Choose a channel featured in the header of iMechanica: 

I am getting started with ABAQUS, and so far, I have had to assign a section property to every part of the assembly, which takes a long time for large assemblies. Often the entire assembly has the same section assignment. Is there a way to assign the same section to various instances?

 

I thank you all in advance.

 

 

defining points in 3d, changing coordinates system ABAQUS script

hey guys please help me, 

 i need to define my revolution points i.e. the circle by x.y.z. coordinates and i dont know how to do that.

 if that is not possible please tell me how can i change the system to cyclindrical coordinates please.

 i
have to draw a spring and for that i know the points in cylindrical
system. i cant define in 2d as for less than 90 degree it will not be in
xz or you know like that plane. it will also be helful to define plane
if i can.

output of abaqus

In the output of abaqus, why there are more than one stress values at the same time?
Thank you so much.

transverse compressibility in Abaqus SC8R elements

Does anyone know if Abaqus SC8R elements have transverse compressibility \epsilon_z?

What properties shoud I specify for SC8R elements, type: lamina, or type: Engineering Constants ? (note that type lamina do not have transverse modulus E3)

Plywood box under pressure on ABAqus

 

Hello everyone,

 

I am working right now on a plywood box simply supported by wedges under a uniform pressure of 1 MPa.

The pressure is applicated through a rigid shell part layed on the top of the box ( a surface to surface contact). The bottom of the box is on contact (surface to surface) with the rigid shell wedges (2 on the corner of the box and 1 on the middle).  

As a boundary condition, all the DOF's of the wedges are constrained.    

Drucker Prager model for Silicon dioxide powder in ABAQUS

Hallo, everyone,

I am PhD student in material processing. I have a project of using silicon dioxide powder as forming media for tube hydroforming process. I read some literatures about the material model of granular materials. It seems that the Cap model in ABAQUS should be suitable for prescribing the material behavior in FE model. But it is not easy to do the triaxial test for silicon dioxide powder.

Minimum length scale in ABAQUS

Free Tags: 

Dear all,

This might be a simple question. What is the smallest length scale that can be simulated in ABAQUS. I am trying to run some continuum estimates for particles with dimensions in the nanometer range (10 to 50 nm). Is it possible to specify such length scales in ABAQUS?

Thanks for your insights.

How to get inside the ABAQUS incremental/nonlinear static solver

Choose a channel featured in the header of iMechanica: 

Hi guys,

I'm working on an ABAQUS extension/plug-in of a sort and I'd like to replicate results for a single 4-node plane stress element produced by the ABAQUS incremental/nonlinear static solver.

I assumed the relationship is:
t[K] {Δx} = t+Δt {P} - t{F}

ABAQUS/ Explicit help

 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.

Abaqus- non uniform pressure load in 2D

Hi all,

 

I am new to Abaqus and I found the problem I unexpectedly cannot solve.... My case is quite simple- I have 2D frame, part of which is under nonuniform pressure distribution (described by linear function). When I create analytical field referring to previously created local CSYS, apply a load in 'static general' with distribution determined in analytical field and try to run a job, i have a message:

Report generation in Abaqus with Mode shapes

Choose a channel featured in the header of iMechanica: 

Hi,

I am performing natural frequency analysis on a cylindrical structure in Abaqus. I am extracting about 80 modes (considering the presence of symmetrical modes). I want to generate a report with all the mode shape patterns and corresponding frequencies listed. Is there any way to do this automatically? Taking Prnt Scrn and generating word document is consuming lot of time and also I have multiple model combinations to do such analysis.

Thank you in advance.

weird error in Abaqus

Hi,

I am encountering a weird error in ABAQUS analysis. Their is no information in the files about why this error occurs, the execution just terminates all of a sudden. Following is the error:

Extracting boundary conditions from output database (odb) file using ABAQUS scripting

Hi,

I am familiar with abaqus python scripting to create odb files and to extract nodal data from an output database (odb) file in ABAQUS. I would like to know whether it is possible at all, to extract the boundary conditions from an odb file. I guess that the boundary conditions are not stored in an odb file. But I am not sure. Any help in this regard ??

Does anyone know things needs to know before doing dynamic analysis using umat

how to import subroutine file in abaqus software ?

Sir,

 I am new to abaqus software. How can i import a subroutine file into abaqus software.while running a .inp file  added to job it asks for a sobroutine file.while editing the job file in general tab there is an option to include a subroutine file but while selecting a .f file to it. it asks for importing a .for or .obj file . what can i do now. I am studying about heat generations due to friction in contacts .the .inp file i imported into job is ufricxxy.inp and .f file is ufricxxy.f from help .please help me in solving these problems.

 

thanking you
