Failure of railway axles has been the problem which gave origin to the studies about 'fatigue'. The modern approach to the structural integrity of these safety components is to complement the traditional designwith a 'damage toleranc' analysis.
hi!
i am interested in the fatigue crack growth of a cracked body.Recently,i am stucked by a problem of how is the stree-strain relationship near the crack tip under cyclic loading.As we know,the HRR field near a crack tip under monotanic loading is well solved.So,i doublt that if the type of the HRR formulation can still be used under cyclic loading.If not,why?And how to solve this problem?if there is any suggestions or references ,i would be appreciated!
Does Anyhone have any idea about fliping the normal directions for a solid sections to be pointed in not out, because am having an error: nodes have incorrect normal definitions.

I want to work on delamination and cohesive zone model. I would also like to model this in Abaqus. I’ve read the material available there but it’s not adequate. I would like to know the concepts and fundamentals of the cohesive zone model and its implementation. Can anyone explain this? Please suggest some good literature/books on this for beginners.
Praveen.

Hi everyone,
I am new to ABAQUS. I am working on a research topic where I need to study the temperature increase arised due to strains applied to a body. From the user's manual I understood that I need to use "Sequentially Coupled Thermal-Stress Analysis" for my model.
