Calculating Cyclic Energy from Acceleration (Relative)

Click For Summary
SUMMARY

This discussion focuses on calculating cyclic energy applied to a material under two distinct conditions: 1G at 0.1Hz for 47 days and 4.5G at 60Hz for 3600 seconds. The user, Munnaz, seeks to determine if the energy from these conditions can be directly compared or related. The conversation highlights the importance of understanding the nature of the accelerations, specifically whether they are peak-to-peak or involve additional stress factors, as well as the context of the forces applied, such as on a vessel versus a vibrating table.

PREREQUISITES
  • Understanding of cyclic energy principles
  • Knowledge of acceleration and frequency relationships
  • Familiarity with material stress and strain concepts
  • Basic physics of forces in different environments (e.g., ocean vs. vibrating table)
NEXT STEPS
  • Research methods for calculating cyclic energy in materials
  • Study the effects of varying acceleration on material fatigue
  • Explore the relationship between frequency and energy in dynamic systems
  • Investigate the impact of environmental conditions on material behavior under cyclic loading
USEFUL FOR

Engineers, material scientists, and researchers involved in material testing, particularly those focused on cyclic loading and energy calculations in dynamic environments.

Hello,

I am looking at relating two situations under which cyclic energy is applied to a material.

Condition 1: A material has been subjected to a force of 1G at 0.1Hz for 47 days.
Condition 2: The same material has been subjected to a force of 4.5G at 60Hz for 3600Seconds.

Is it possible to calculate the energy applied under both conditions and relate them to one another (i.e. condition 1 has applied 200% the energy applied under condition 2)?
or
Can they be directly related to each other. For example: Under condition 1 the material experiences 406,080 cycles therefore a cumulative total of 406,080G. Under condition 2 the material experiences 216,000 cycles therefore a cumulative total of 972,000G. Therefore condition 2 experiences 240% times the energy condition 1 experiences.

Is either of these possible or is there another way to relate them to one another?

Thanks in advance.

By "cyclic energy" do you mean that the material was spun in a centrifuge at the indicated acceleration?
 
Hi Dale,

Not centrifugal force. Condition 1 is on board a vessel in the ocean and the other is on a vibrating table. Both vertical accelerations.

Regards Munnaz
 
So if the accelerations are vertical and they are cyclic then the magnitude must vary over time. So is the 1 g mentioned a peak-to-peak acceleration or what? Does the material free-fall down?

Also, does the acceleration involve any "squeezing" or "flexing" of the material other than what happens simply due to gravity and being pushed up? In particular, the vibrating table does not seem like it could be done without some additional fixation and stress in the material.
