where nb is the number of different stress levels, ni is the number of loading cycles accumulated at stress Si, Ni is the average number of loading cycles to failure at stress Si. Failure occurs when the fatigue damage ratio DF reaches 1.0. Service loadings in the majority of OWT support ...
users can quickly iterate their design and see instantaneous physics feedback and engineering parameters, like equivalent stress and factor of safety. With those two known values, engineers can quickly know how close they are to the threshold of material failure. ...
This stress trend is also illustrated in a normal stress profile along the axial direction inFig. 11.12. Looking at the lowest testing temperature at the non-heated area, no failure or cracks should occur. However, it can be observed from the microstructure of the sample that a large number...

For large triaxialities void growth is the dominant failure mode, while at low stress triaxialities between above two regimes, fracture may develop as a combination of shear and void growth modes. 展开 关键词: Fracture Stress triaxiality Experiment Numerical simulation ...

It is supposed that strain energy w at a per-unit volume is a function of total equivalent strain Eeq, w=w(Eeq). Thus, total equivalent stress Σ is defined as (3.2.45)Σ=dw(Eeq)dEeq Substituting w(Eeq) into w in Eq. (3.2.34), the solutions are given by (3.2.46a)σ′=23Σ...
In the used probability of failure Pf approach, the Pf of elements when the thermo-mechanical transverse stress in the layer changes from 0 to σT is equal to the number of broken elements,(3)Pf=ρρmax=1-exp-σTσ0mwhere ρ is the crack density at stress σT and ρmax is the ma...
