Research on the Rule and Life Prediction of Tooth Root Crack Propagation based on Fatigue Experiment and Numerical Analysis Method

Jixie chuandong, 2022
Through the fatigue test of modified spur gear with root crack fault by fatigue testing machine，the rule of root crack propagation is obtained，the root crack is easier to expand along the direction of tooth width than the direction of tooth root， and the

Vision‐based fatigue crack automatic perception and geometric updating of finite element model for welded joint in steel structures

Computer-Aided Civil and Infrastructure Engineering, Volume 39, Issue 11, Page 1659-1675, 1 June 2024.
Abstract Digital twin requires establishing a self‐updated model to simulate the structural damage perceived onsite. Despite the great success in damage identification and quantification, the difficulty in registration still limits the efficiency of model updating.

Potentials and limitations in finite element based crack propagation analysis using FRANC3D [PDF]

, 2020
About 80% to 95% of all structural failures occur due to a fatigue mechanism1. Accurate fatigue assessment is therefore of great importance. This thesis focuses on a finite element analysis based approach, implemented in the program FRANC3D, to ...
