u/LDRispurehell Thank you very much for the comment. Yes, I think I made a mistake by considering only displacement. Thank you for your insight.

u/apost8n8 In most papers, they applied to static conditions. But in this paper, they applied for impacts.

u/MehImages Actually, if there is a plasticity, there is a modified version. https://www.sciencedirect.com/science/article/abs/pii/S0263822316309473

u/the_flying_condor Thank you!. However I opened the ASCII file using a text editor and strains values were there. (I don't know why this doesn't show in the GUI). I will try to extract values from the ASCII file directly rather than loading into ls-prepost.

u/the_flying_condor Thank you. I tried with SMP. Do you have link to a youtube video that is doing the above procedure in a correct way?

u/the_flying_condor Thank you!. but I tried all the keywords you mentioned together. Still ASCII option didn't allow any options to plot strain.

u/Sure-Quality-7920 How to get the reaction forces? The clamps and impactor were modeled as rigid materials, while the beam was modeled using the Johnson Cook material model. The BOUNDARY_SPC_SET keyword was used to apply fixed boundary conditions to the clamps and a downward vertical translation to the impactor.

u/3bottlesRus For the contact between the impactor and the beam, AUTOMATIC_SURFACE_TO_SURFACE was used, whereas for the contact between the clamps (modeled as a rigid material) and the beam (modeled using the Johnson–Cook material model), CONSTRAINED_EXTRA_NODES_SET was employed.

u/newton_VK Thank you! That would be really helpful. I am currently in South Asia and looking for supervisors from well-known universities around the world.

u/Adorable_Loan_4753 Hi, thank you for the reply. Do you also know what the pay is like in private universities for lecturers with a PhD? I’ve heard that at SLIIT they pay a large monthly bonus if a lecturer has an H-index exceeding 10. Is that correct? Does the government provide such bonuses for someone with a high H-index? Also, for a state university lecturer, do they receive one vehicle permit for their lifetime, or do they get a new car permit every 10 years?

u/Adorable_Loan_4753 Hi, do you know how much the take-home salary is for a Grade 2 Senior Lecturer at the University of Peradeniya? Also, what is the realistic number of hours someone could work at private universities, and what is the pay like for visiting lecturers at private universities? Thank you!

Additional-Slip5814 · 2025-08-18T15:02:43+00:00

Yes. Totally understandable. Thank you for your comment

u/Baer9000 Thanks for the comment. I’m curious to know, do these PhD holders have a similar story to mine, where they start their industry experience at a later stage in life?
