FEA simulation of double joints in shear loading

Choose a channel featured in the header of iMechanica: 

Hi all,

 

I have a question about an FEA simulation. Particularly, about the boumndary conditions that need to be applied to run this simulation. 

 

attempt1:

 

I fixed the right end of the plates and applied loading to the left end. This resulted in stresses go through only the top joint region (W1 in figure attached). 

 

From our understanding, the deformation is got to be symmetric on both the plates. But, when we applied these BCs, it is not smmetric. 

 

 

attempt-2:

Namaste from India.Jay Naik here. I am Post graduation Student doing Specialization in Machine Design.I am Doing My project in Master in area of" Design of storage tank" in One of the reputed company in Static Equipment Design.Any Idea on which Software(Fea or failure analysis) Design of storage tank is carried out?I have heard about AMETank and Ansys.

Secondly i am carrying out Literature review Present days.reading API 650 and other standards.Suggestion requires in this area.

Please guide me in proper manner.in which way i should carry out the project in systematic way.

Plane_Stress, Plane_Strain and 3D - Simple doubt..

Choose a channel featured in the header of iMechanica: 

Hello everybody,

 UPDATE :   Question can be deemed as closed.. :)

                       I have a very simple doubt in 3D model simplification. I believe plane stress and plane strain conditions are the two extreme states to simplify a 3D model to 2D case.

Crash Test Bench

Hi I am working on the designing of a crash test bench to measure vehicle door intrusions ?

Could some one provide me basic ideas on the test bench set up and how to mout the door on the test rig and which degrees of freedom to lock ?.

ABAQUS - increase the size of the interior elements

Free Tags: 

Hello everyone,

I am currently working on modelling ITZ zones in concrete 2D microstructure. ITZ is the cement paste zone near the surface of aggregate which differs in properties from bulk cement paste. The thichness of ITZ zone ranges from 10-50 micrometer (0.01 - 0.05 mm). The size of RVE I am using is 100X100 mm which makes ITZ a very fine detail in my microstructure. I have created a instance in abaqus merging all parts, Aggregate, ITZ and Matrix( Cement Paste).

I seeded the instance with using these parameter:

Do you know how to model fork support?

Do you think this is correctly modeled as fork support (picture)

minor axis bending- restrained, torsion - restrained , free to warp

 

 

Lateral torsional buckling of I beams with restraint

I am looking to model buckling of I steel beams with restraint in abaqus. But I do not know how to make rigid connections between the steel members. 

 

Why is the other beam( beam with fixed supports) not stressed? How do i define contact between the two beams.

3D FEA of stress concentration

Dear all,

 

I am simulating tensile specimens with an elliptical pore(representing a flaw in the material) in the mid-cross section of the specimen. What I am looking for is the stress concentration caused by this pore.

I am simulating this as a 3D specimen under tensile loading only, with 3D, 8-node linear brick elements(1st order). Now my questions are:

1- Is there any analytical solution for such problems(3D with elliptical pore) with which I can compare my FEA results?

how to model fastners in ABAQUS

How to model Fastners in Abaqus? I have an assembly which are connected by more than 500 fastners and has angle and channel sections? 

IS there a method to do in ABAQUS?I have assembled my model in SOLIDWORKS by providing Concetric mating for all drills, but haven't included fasteners there as that will again increase the simulation time.

PREDICTION FOR DEFORMED PART WITH TIME

Dear ALL,

Does anyone here has an experience carry out  FE analysis for a part[bracket] which was deformed plastically during cyclic loading test.

I'm now working to resolve this issue when a bracket was fail to withstand the constant loading of 500N during cyclic test. It was reported fail at ~3800 cycles which was less than target.

Rgds.
