I need all surfaces for the contact. What is tangent propagation? Thanks

I created a screw in bone block model. The screw has a helical thread on it's surface and the hole in bone matches the surface of the screw. I am trying to create a surface to surface contact interaction between the screw and bone but I do not know how to select the "whole surface" of the screw...

I've finally figured out how to do it. Thanks!

I successfully partitioned the body into two layers but when I try to assign properties it still selects the whole body instead of each section separately.

Isn't there a different way? a composite layup or something similar?

The tie constraint worked well for me. But now I want to use the surface to surface interaction. I tried to do it but it failed to converge. There are a lot of parameters which I don't really understand, can anyone help me with this model please?

Hi, I am trying to model a bone block with 2 layers with different material properties, cortical bone and cancellous bone. The two layers should act as one body. How do I do that? Thanks

I tied the two objects by defining their surfaces and creating a new tie constraint. I did not define any interaction. Now when I apply a concentrated force on the screw, the results show the stress profiles on the screw but nothing on the bone, any idea why?

Is there a way to mesh the assembly altogether so that the nodes will be connected? Do they have to be connected anyway or would the Tie constraint solve the problem? Thanks a lot

hi, I am testing the stresses in bone around screws mechanically drilled in bone. I drew screw and bone block models in Solidworks and then imported the X_T files in abaqus. I have a few questions on my model: 1- How can I drill the screw hole in the bone block? I used the merge/cut command...

I used the repair tools to merge surfaces and it worked fine. Thank you very much

Hi, I am a newbie and I am trying to learn the basics. I am doing a FE study on miniscrews in bone. I drew a 3D model of a screw in Solidworks. The design includes a helical modified buttress thread which is necessary for the analysis. When I load the x_t file in abaqus I get the following...

I could achieve what I wanted. Thanks to your help guys... I really appreciate it :)

I am asking about physical rotation of the object not just for viewing. What I am wish to do is the following: I drew a screw, now I wish to draw a block and drill holes in the block matching the exact shape of the screw. I need to rotate the screw so that I make holes at different angles to the...

I know these are some really basic questions but I appreciate your help since I started using SW less than a month ago. I am using version 2008 SP0.0. 1- How do I resize a part proportionally and unproportionally? i.e. change length but not width or vice versa? 2- How do I translate/rotate a...
