In the latest issue of Gear Solutions you’ll find an “Analysis of Tooth Interior Fatigue Fracture Using Boundary Conditions from an Efficient and Accurate LTCA” written by SMT’s Baydu Al and Paul Langlois.

This paper demonstrates a modification to the analysis of Tooth Interior Fatigue Fracture, as implemented in SMT’s MASTA software, in which Loaded Tooth Contact Analysis (LTCA) results from a specialized 3D elastic contact model have been utilized to determine the load boundary conditions for analysis of Tooth Interior Fatigue Fracture (TIFF) to the method of MackAldener.

In contrast to MackAldener’s method, using finite element contact analysis, this method allows for quick analysis times for the calculation of the stress history leading to fast optimization.
