Hello,
I am looking for an explanation about the formulation used for CONTINUMM SHELL elements in ABAQUS.

Buckling and Post buckling of Plates

Hello every one.
I'm doing work on buckling analysis using abaqus. I want to continue my work on postbuckling of plates also. I'm not getting any tutorials on how to perform Postbuckling analysis of plates using abaqus. When i searched the abaqus help documentation, i got .inp file of a plate, but i didnt get the steps on how to perform the analysis.
I read in some books that after buckling of a plate, it still can take the load. How to do this in abaqus interface ?how to perform the postbuckling analysis in a proper way ?
Plz help
Beam-Shell contact in Abaqus

Hello everybody.
I am doing my diploma project and I have to model an off-shore oil-rig in Abaqus. It's a metallic truss-type system. I've defined all of the elements composing the structure as wire elements and the decks as solids. Does anybody know how to define the contact between the decks and the supporting beams? The decks are supposed to be bolted to the beams.

[FEM] How we are using shell geometry properties in time of calculation?

Hello.
I'm interested in methods and approaches for FEM, that are used for taking into account the shell geometry properties (curvatures, quadratic forms) in time of calculation. I'm not telling about NURBS, the shells are defyned by analytical expressions: sphere, Monge surfaces, Joachimstahl surface. In Zienkewich book they are use the flat elements, but in time of calculation they don't use the shell geometry, only for mesh generation. Maybe someone somehow have used in shape functions the coefficients of quadratic forms...
Layered Shell Displacements
Hi,
I am confused regarding displacements calculated through layered shell model in Ansys using Shell 181.
The model is composed of 5 layered sections of different materials (with thicknesses) assigned to an area. The whole laminate is cooled from a reference (zero-strain) (150 C) temperature to a uniform temperature (-40 C).
I need to calculate the difference of displacements between two nodes in the meshed area, for a specific location in layer no. 3. The issue is that I only have nodes in one plane and the results (i think) are interpolated along the thickness. My question is that, is there any method to find displacements at a specific layer in the shell model [as we can find all other results (stress, strains etc.) for different layers]
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.
How to Combine Shell Element and Solid Element in ANSYS
Hello Everybody
I'm currently working on on the tubular weld of joint modeling using ANSYS
Problems that I faced was how to combine elements of the shell (for chord and brace) with solid elements (for weld) so that stress transfer can occur between two elements
one technique that I know is using MPC
is there any among you who has a tutorial about it ..?
please help.....
