| Research Abstract |
(1) Deformation and loosening behavior of bolted joints ; Clarify the slipping behavior of bolted joints under transverse loading, and present the evaluation methods of loosening criteria.
(2) Evaluation of fretting fatigue strength and fatigue life ; Present the fretting fatigue crack initiation criteria using stress singularity parameters, crack propagation behavior using fracture mechanics and low cycle fretting fatigue life using critical distance stress theory.
(3) Compiling above two results "CAE modeling, analyzing and evaluation systems for jointing structures" were presented and pushing forward the spread of these systems in industrial fields.
