Indeed, the built-in STL Import plug-in creates a new model but you can copy the part from it to another model with the Copy Objects tool.
If you want to generate a solid mesh for a part imported from STL file, you have to convert that part to geometry (since it's imported as orphan mesh)...
Cohesive contact is meant to replace the adhesive so that you don't have to model it directly but you don't take its thickness into account. It's just a sticky contact property.
Are you sure the nodes are shared and not only coincident ? You can achieve that with the Edit Mesh tool.
Contact...
In practice, you can use XFEM in Abaqus to model bulk crack propagation with crack location independent of the mesh. It can be used together with CZM or VCCT (delamination in conjunction with bulk crack propagation). Crack path and location don't have to be predefined.
For more details, check...
I would try cohesive contact first (it’s much easier to define than cohesive elements) but you can’t account for the thickness of the adhesive this way.
Both approaches to attach cohesive elements (tie constraints and shared nodes) are correct and should give equivalent results. One advantage...
Are you sure you specified the step and increment numbers correctly and that nodal temperature data is available for those increments ? If you omit those numbers, Abaqus will begin reading the data from the first increment of the first step in the referenced odb. Does it work in such a case ?
Did you check the documentation (chapter "Smoothed Particle Hydrodynamics", paragraph "Artificial Viscosity") carefully ? Artificial viscosity is, as the name suggests, not meant to model real viscosity. It serves a similar role as *BULK VISCOSITY in Abaqus/Explicit and it’s definition is also...
Segmentation fault usually means a bug in Abaqus or an issue with the computer (the latter might be the case here if the same Abaqus version was used).
This would normally cause a different message but it's often the case that analysis fails because of insufficient disk space for scratch data.
You can't have such overlap between the parts unless you use the embedded region constraint. Otherwise, you would have to make cutouts in soft tissue for bones. If you want to account for the presence of soft tissue at this level but on the side of the bones, 2D model won't be appropriate. It's...
Indeed, crack propagation direction can be calculated only for homogeneous isotropic elastic materials. Details and references can be found in the Theory guide in Abaqus documentation (chapter Prediction of the direction of crack propagation). You could try using subroutines to get this result...
Basically, it’s Newton’s third law of motion. With those output variables, you can get the reactions to applied loads which is very important when checking the results.
