I plan to run analyze a locomotive body structure for + (or) - 20 % vertical loading and use eurocode for aluminium structures for damage calculation .
I plan to run the model for +1.2g and 0.8 g in abaqus.
To calculate the stress range
I plan consider the max principal stress for 1.2g...
I need to evaluate a structure for fatigue. The cyclic load give is +/- 20% of vertical acceleration load.
My Approach :
I am planning to use equivalent stress range approach as per euro code 9 guideline for aluminium structure.
(Following euro code guideline for fatigue assessment is an...
@rb1957 yes the car body is also analyzed for fatigue . Its for 5*10^6 Cycles ,after running the model for +/- 0.15 g.How to consider the stress range ? how do i calculate fatigue for welds? The analysis has to meet eurocode 9 guidelines.
How to carry out fatigue calculation for locomotive car body structures ? Which method is preferable Equivalent stress approach or Linear damage calculation ? The method has to be inline with eurocode design guidelines . I have carried out the fatigue load case with +0.15 g and -0.15 g, how do...
Hope you are doing well.
Recently i carried an analysis - For same loads and boundaries
First iteration with
*STEP, NAME = Step-1, NLGEOM = NO ,PERTURBATION
Second Iteration with
*STEP, NAME = Step-1, NLGEOM = NO
*STATIC
0.1 ,1.0 ,1.0000E-05,1.0
My analysis has only one...
