In recent years, by the spread of general purpose Finite Element Method (FEM) analysis software, anyone can carry out FEM analysis now and can grasp the stress state of a structure. However, in order to grasp the influence on a stress state when some shape parameter has changed, FEM analyses for each shape are required, and it requires long time. As an example of this issue in fatigue strength design, the relation between the plate and rib in a T-shaped structure, containing a corner, is analysed. The stress concentration factor or stress intensity factor between these two connected shapes are analyzed by the FEM, and a method of approximating the stress concentration factor and stress intensity factor in an actual shape is proposed. Then, the proposed FEM-based method was validated through a comparison of the results obtained using this method for shapes of finite dimensions with existing analytical solutions for shapes of infinite dimensions..

3. Shigeru Hamada, Minjian Liu, Measurement of effective stress intensity factor range of mode II fatigue crack growth using
hysteresis loop, 13th International Conference on Fracture, 2013.06, A method was proposed for measuring the effective stress intensity factor ranges of Mode II fatigue crack growth by using the hysteresis loop for a specimen's surface strain. Many cases of rolling contact fatigue failure, such as those that occur in railway rails, bearings and gears are due to repeated high shear loads. In order to prevent such fatigue failures, the resistance of a material to repeated high shear loads must be determined. The fatigue crack growth characteristics are dependent on the Mode II stress intensity factor range. However, conventionally measured Mode II fatigue crack growth characteristics vary according to the measurement methods. Therefore, the authors improved the experimental measurement method proposed by Murakami, and proposed a way to measure the Mode II effective stress intensity factor range. Improvements to the jigs and specimen were made based on the ideal mechanical model of the experimental method. Furthermore, to measure the Mode II fatigue crack growth behavior, strain gauges were applied to the specimen and the hysteresis loop of the strain was measured with high accuracy by using a newly developed subtraction circuit..
