Likewise, the same is true for using formulas in failure criteria and fatigue analysis. One needs to extra attention as to which reference/nominal stress is used before applying these stress concentration factors. The stress concentration factor calculators presented in this section calculate both K g and K n, whenever possible. However, for some elements at the outside. By terms of the numerical modeling of ABAQUS software, the analysis of the stress concentration factor (SCF) of tubular T-joints subjected to axial load is. Stress concentration factor defined in this fashion is called K n. When I apply a load of 2000N to the centre of the femoral head (as a distributed load), I obtain for most elements a realistic stress of around +- 2 Mpa. Stress concentration factor defined this way is denoted as K g another commonly used reference stress is the nominal stress over the cross section area at the location of the stress concentrator. Asked 22nd Nov, 2013 Asgar Mohamadzadeh Stress intensity factor in abaqus. One of the most commonly used reference stress is just the (gross) stress in the same element under the same loading conditions without the stress concentrators (holes, notches, shoulders and so on). How can I find stress intensity factor in abaqus Question.
