Dear all,

I am starting to use VFRICTION subroutine in ABAQUS. But the manual examples are very simple.

To start, I would like to implement the friction law that already exist in ABAQUS(penalty e.g.) to see how this subroutine works.

I do come across the ABAQUS Technical notes about subroutine FRIC in standard which explained the implementation in detail. I wonder if someone happen to know whether similar technical notes exist for VFRICTION in explicit or have experience working on VFRICTION before?

Any help will be very appreciated.

Hi, I am looking for the post-doctoral position in structural dynamics ( instability of the thin structures, shell theory,  composite structures, static and dynamic buckling of the shells). I am currently a Ph.D. candidate in the Nonlinear Mechanics Laboratory at Indian Institute of Tehnology Kanpur (India) where Dr. Pankaj Wahi and Dr. Sovan Lal Das have adviced my research for the past four years. My PhD thesis deal with the shell theory and dynamic behavior of the shell ( especially thin-walled circular cylindrical shells).

Hi friends,

I have a model in solid works to has three laminate. I want to create the model in ansys. I saved it with suffixes parasolid, iges and step But ansys didn't show it. How can I Import it in ansys? please help me.

can I import this model in workbench and then create it in ansys? How should do this work.

model is showed below:

Hello Everyone,

Whats the formula or equation to find flexural wave propagation speed along the beam??

Please help me with this,I am kind of stuck in this problem.
Thanks in advance.

Hi friends,

I have a shell with multi thickness in ansys But I don't know to how should describe multi thickness in section command in APDL Ansys.

my model in solidworks is attached:

please help me.
