C1,c2,c3,c4

Hi,

My email address is [email]waqas.hf@gmail.com[/email]

Well as for my problem, i am working on a pressure vessel exposed to fatigue loading. When i check the abaqus manual, c3 and c4 make sense BUT only for delamination problems. In my case (bulk material) i am not sure that c3 and c4 mean the same. In my opinion they might be fatigue ductility coeffciecnt and exponent respectively. C1 and C2 in my case might be hardening coefficient and expoenent respectively too.

Just send me your thesis and references from where you captured c3 and c4. Exchange your email with me and i will send you a report that made me think that c1 to c4 might be ductility and hardening properties. Lets solve the problems together 🙂

[QUOTE=hernang,9878]Yes you are right about c3 c4, I have some examples and can let you know how to get them, I could send you my thesis (draft) document which Im working on, it explains how to obtain them, also the paper from where I took the values, Can I have your email address?

regarding c1 c2 I have absolutely no idea... Ive been trying to find the for over 2 months now, I contacted Abaqus representative for my company but they said they only have the help available...[/QUOTE]

Dear All,

I am also struggling to find how to define the c1, c2, c3, c4 parameters for Low Cylce Fatigue in Abaqus. Would any of you be able to help?

Hi

It is supposed that the load reduction rate change by changing c3 and c4 but in my model, I tried a wide range of values and the load output is identically the same. could you please advise with this

Thanks
