Find Yield displacement and Yield strength of steel under cyclic load

Click For Summary
SUMMARY

The discussion focuses on determining the yield displacement and yield strength of steel under cyclic loading conditions. The user has conducted experiments involving metal bars and has collected data on hysteresis loops representing "Load vs displacement" across 13 steps, each comprising three cycles. The objective is to calculate dissipated energy, stiffness, and the damping ratio based on the yield point and yield strength of the steel. Participants emphasize the necessity for the user to present their experimental data for more effective assistance.

PREREQUISITES
  • Understanding of cyclic loading and its effects on materials
  • Familiarity with hysteresis loops in material testing
  • Knowledge of yield strength and yield displacement concepts
  • Basic principles of energy dissipation and damping ratios
NEXT STEPS
  • Analyze the hysteresis loops to identify the yield point of steel
  • Calculate the yield strength using the data from the experiments
  • Research methods for calculating dissipated energy in cyclic loading
  • Explore techniques for determining the damping ratio in materials
USEFUL FOR

Materials engineers, structural analysts, and students involved in experimental mechanics or materials science who are seeking to understand the behavior of steel under cyclic loads.

TL;DR Summary: I have experimented metal bars under cyclic load, you can find the picture attached of the hysteresis loops of "Load vs displacement" of the experimental work... 13 steps (each step 3 cycles)
Now I want to find the point where the steel started yielding and the yield strength so I can calculate dissipated energy and stiffness and also the damping ratio.
If you have an idea, please help, I may provide more details if needed.
Appreciate your help.

Yes, it's
that's the work, you want me to share the data from the experiment. or What do you mean?
 
I'll go ahead and move it to the schoolwork forums for you then.

No, it's your schoolwork, so you must show your work. We cannot help you until you show your work on your schoolwork problem/project.
