Hysteresis loop
Hi,
Does anybody know how to plot the stress-strain (check the strain rate effect) and hysteresis loops by using Abaqus?

Elastic-plastic analysis
Hello Everyone,
I am a beginer in using Abaqus. I am going to model a nothed specimen subjected to cyclic loads, to investigate the stress/strain distribution and so on. I would appreciate if you guide me.
Research statement
Hello All Researchers,
I'd like to know your opinion about some key points that make a research statement so effective. There are so many information, tips and advices in the internet. But, I am looking for your personal experiecne to write simple, quick and effective research staement. I would appreciate if all of you share with me some your tips.
Best Luck,

fracture analysis using ansys
Dear all,
I am doing a fracture analysis of composite beam using ANSYS please let me know about the type of elemnt that i should use for meshing?
thanks in advance
Fatigue Crack Growth Under Spectrum(Random) loading
Dear all Researchers,
I am writing regarding for the first time about the UAA(Unified analytical aspect) on Fatigue crack growth. The idea of this technique is this question : too many fatigue life prediction relations but still those are not perfect. on the other hand, new math ways still have not been the classical fracture mechanics. I am looking for some comments as response to this concern. Clearly, how we upgrade fracture mechanics theory using atomistic development in modeling fatigue propagation?
Let us talk about this.

Sequence loads
Hi everybody
I want to ask you regarding the general pattern of diagram da/dn Vs. DeltaK(stress intensity factor) for Variable amplitude loading? Could we share our knowleadge in this case?

crack closure tip model
Hello, my question meaning that developed crack closure model can be explained the damage interaction among cycles of loads, is it right that each cycle has a own damage how can interpolate the overall dame in realistic as possible? which model do you suggested that can be contribute in this issue consider crack closure model?
notch tip radius
Hello everyone,
I am looking for a way to measure notch tip radius experimentally. Would you give me some ideas about that? is there any relationship between morphology of notched cracked body surface and notch tip radius?
Thank you and Regards,
New idea in fatigue problems
there are two analytical concepts that are very important in fatigue failure.the first one is crack closure and the others is residual stress .the first one is in behind of crack and the other emphasis in the front of crack tip. the question is if we use some devices such as AFM/SEM is it possible we model the energy filed during fatigue process? if this idea can be investigated the second question can be asked: is there any similarity to model for different loading conditions?
I appreciate if you also put your comment in my idea?
Piezo ferroelectric materials
