NiTi Rotary File Deformation FEA

I need a finite element analysis that concentrates on how nickel-titanium rotary files deform while they are cleaning and shaping root canals. The work revolves around capturing realistic clinical loading—torsion, cyclic bending and combined stresses—and converting those conditions into a reliable 3-D simulation.

I will supply the CAD geometry I currently use chairside, plus any torque-speed data recorded from the endodontic motor. You would:

• refine or rebuild the mesh so the file’s variable taper and helical flute are accurately represented,
• assign appropriate super-elastic NiTi material properties (including transformation strains),
• apply canal-wall contact and a rotating-bending load path that mimics the shaping motion, and
• deliver contour plots, quantitative deformation results and a concise written interpretation of where excessive flex or plastic strain is likely to initiate.

The study is complete once I can compare predicted tip displacement and strain distribution against my empirical observations from high-speed video and discarded files. All modelling can be performed in ANSYS, Abaqus, COMSOL or a comparable solver—as long as the final files and a brief methods report are shared so I can replicate them later.
