Thank you very much for your comprehensive video. regarding the measurement of residual stress, I’m not sure which stress I should take into account during the unloading step as my residual stress. I think due to the movement of the pin in two directions of X (horizontal movement of the pin with constant velocity) and vibration in Y direction. It generates a complex residual stress state. Hence I might take into account the von Mises stress as my residual, but Im not sure about that. I would be grateful if you could elucidate my doubts regarding this matter. Thank you in advance for your time.
Hi. You are welcome. As all of the components of stress are present in your simulation, to do every interpretion or investigation including the calculation of residual stress, you must use Von Mises stress. Also you can use max and min principle stresses. But most of the time they are used for damage initiation detections.
Hi. Please check the Abaqus documentation. There is a section in Abaqus documentation for explaining amplitude. In that section it is mentioned that: omega=2*pi*f Abaqus uses omega for periodic amplitude based on Fourier series. In our problem f=100Hz so omega=2*3.14*100=628 rad/s All of our tutorials are based on Abaqus documentation and even we have a tutorial for how to use it.
@@FemexIran sorry, but when you insert the amplitude, clearly says circular frequency. Circular frequency is different to angular frequency. Is the amplitude input window wrong? Please see your video at 10:40 and you will see that the input window clearly says circular frequency. If this is wrong, it should be good to report this mistake to Simulia. It is not my intention to disturb you. As a matter of fact I think your videos are good. But here there are a problem. Thanks.
@@mariogalindoq Your problem is that you do not read the Abaqus documentation. Please read this section in the Abaqus documentation version 6.14 which is available in Google: Abaqus Analysis User's Guide>Prescribed Conditions>Overview>Amplitude Curves The formula is written clearly with an example about periodic amplitude which T=0.2s so f=5Hz and finally omega=10*pi=31.4 rad/s I hope you can finally understand.
@@FemexIran you are right! Abaqus refers the angular frequency as circular frequency. I think this is a mistake in Abaqus because in the literature normally circular frequency is in cycles/second and angular frequency is in radians/second. Thank you for your patience.
@@mariogalindoq You are welcome. Unfortunately there are a lot of bugs and mistakes in Abaqus and they make working with Abaqus even harder. Our tutorials are based on Abaqus documentation and we are sure about every thing we mention in our tutorials because Abaqus consultancy and tutoring are our main jobs not like the others who create tutorials just for fun with lots of mistakes and mislead their viewers.
Thank you for the detailed explanations of the steps. When using a symmetric boundary condition, would it be possible to visualize contours for the other (symmetric) side of the sample in the visualization module and generate symmetric plots for both sides of the BC? I mean the side which is not initially modeled.
Hi. You are welcome. Yes of course. You must follow this path in the visualization module : menu bar => view => ODB display options => mirror tab => select the coordinate system to mirror => apply
Hi. You are welcome. As I have mentioned in the description below the video, you can purchase the package including CAE and JNL files of the modeling. Also to learn how to do the modeling step by step, you can use our online tutoring service. To use this service, you can send an email to me : mirzabozorg71@gmail.com
Hi Sir may i know how can we set in load module this information, cutting speed = 12 m/min, frequency of 2kHz, and vibration amplitude = 10 micrometer. In your tutorial in amplitude, you let the value of amplitude as 0. Need help from you.

At 10:40 you confused angular frequency with circular frequency. You should insert 2 cycles/second instead of 628 !!
Hi.
Please check the Abaqus documentation.
There is a section in Abaqus documentation for explaining amplitude.
In that section it is mentioned that:
omega=2*pi*f
Abaqus uses omega for periodic amplitude based on Fourier series.
In our problem f=100Hz so
omega=2*3.14*100=628 rad/s
All of our tutorials are based on Abaqus documentation and even we have a tutorial for how to use it.
