Finding damping coefficient of material

AI Thread Summary
The damping coefficient of a material can be determined using the log decrement method, which involves displacing a plate and measuring its displacement over time. This method relies on the principle that the displacement will exhibit logarithmic damping. By analyzing the decay of the displacement, the damping coefficient can be calculated. The discussion highlights the effectiveness of this approach for experimental vibration analysis. Understanding the damping coefficient is crucial for applications in material science and engineering.

i have found the damping factor of a plate from experimental vibration.

how can i find the damping coefficient of the material of the plate

One of the more easy methods is the log decrement method. Basically, you displace the plate, release and measure the displacement as a function of time. The displacement should damp logarithmically which can give you the damping coefficient.

Thread 'Race car suspension Class'

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
