Could someone please show me how to calculate the deformation of a pad (ideal material with the same elasticity at all directions) under a cylinder ? Thank you very much.
Studiot said:This is a standard contact stress problem where have you looked?
luuurey said:But how does everyone find out this? It looks like everyone just copy this without understanding.
Studiot said:The question is commonly addressed by mechanical engineers (as with my link).
It is also standard stuff in standard books such as Roark or Pilney
If you are interested in the background then post more details of your application and interest.
For example where do we get the equation from Wikipedia?
Studiot said:Sorry to tell you this but you put something into this discussion.
What do you want to know and at what level?
Studiot said:What was wrong with the link I offered?
The Wiki formula is not the one you want directly.
Do you understand what the symbols mean in it?
cronanster said:As Studiot has pointed out, what you are looking for is in that link. No, it doesn't go line by line on the derivation, but you should be able to work backwards to see where it came from.
Read through that link again, all pages, and if you still don't understand, come bak and ask.
Pad deformation is the change in shape or structure of a material caused by external forces, such as pressure or weight. In the context of calculating pad deformation, it refers to the change in shape of a pad (typically made of rubber or foam) when weight is applied to it.
Calculating pad deformation is important in order to ensure the structural integrity and stability of a material or object. It can also help determine the amount of weight or pressure a pad can withstand before it deforms, which is crucial for safety and performance purposes.
Pad deformation is calculated by dividing the force applied to the pad by its area. This results in a measure of pressure, known as the stress. The stress is then used in conjunction with the material's properties (such as elasticity and stiffness) to determine the amount of deformation that will occur.
The material properties of the pad, such as its elasticity and stiffness, can greatly affect pad deformation. Other factors include the amount and distribution of weight or pressure applied, as well as external factors such as temperature and humidity.
To minimize pad deformation, it is important to choose a material with suitable properties for the intended use and to distribute weight or pressure evenly across the pad. Additionally, regular maintenance and proper storage of the pad can also help prevent excessive deformation over time.
