[ 1 ] - The Effect of Inclined U-Notch Geometry on Mode Ratio (KII/KI) under Mixed Mode (I + II) Loading
In inclined U-notches, the mixed mode (I + II) loading occurs and the mode ratio can be increased by varying the notch angle. In this paper, the effect of the inclined U-notch geometry, i.e. the notch depth, the notch angle, the notch root radius, and the position of the notch with respect to supports, on the mode ratio (KII/KI) have been studied. Three-point bending and plane strain condition ...
[ 2 ] - Study of Variation of the J-integral and the Fracture Toughness in Blunt V-notches under Mode I Loading
Fracture assessment of U- and V-notches is important in mechanical engineering. One can use the J-integral as fracture parameter in order to predict the critical fracture load in notches. The critical value of the J-integral in cracks is a function of the material properties. In notches, however, the material properties as well as the notch dimensions affect this critical value (named fracture ...
[ 3 ] - Evaluation of Thermo-mechanical stress in work rolls of ring rolling mill under thermal and mechanical loading
The defect in work rolls directly influence the forming cost and the final shape of the product. The researchers tend to investigate the thermo-mechanical stress in work roll of rolling machines. These stresses may reduce the roll life. Since the investigation of the thermo-mechanical stress in work roll with real-conditions is complex, comprehensive studies by means of numerical methods are av...
