Converting Force Measurement to Pressure

huion_4156 — Thu, 15 Dec 2022 12:15:48 +0000

A zip-tie like structure squeezes an elastic part. I can measure a force that is related to the squeezing pressure. I need to create a calibrator that would allow me to correlate the force to the squeezing pressure. I have a zip-tie like structure, which when pulled, squeezes an elastic part. Think of it like a having a zip-tie around your finger. I can measure a force that is related to the squeezing pressure. This relationship between force and pressure is quite linear. I would now need to create a calibrator that would enable me to correlate between the measured force (N) to the pressure (Pa) that is imposed to the elastic part. The diameter of the zip-tie is about 22mm and it squeezes to about 17mm diameter. Now, I first started to think that I would have some inflatable balloon with fixed pressure. The zip tie wouldn't move when the pressures match. I would prefer to keep this calibrator relatively simple at first stage, so any crazy, easily built ideas are welcome ;-).

Acoustic vibrations for musical instruments?

Hi,
I am looking for examples of acoustic vibration simulations for musical instruments. Particularly, I would like to do some geometrical optimisation for a guitar case.

True and engineering stress

johngriter — Thu, 15 Dec 2022 12:08:40 +0000

I am a student in mechanical engineering and we graph a stress strain curve. I know what these values are and I even know how to calculate it given the engineering stress and strain, but I just don't understand why it is necessary in the first place to calculate the true stress and strain. Can anyone help?

Stress or Stain life method in fatigue analysis

taasnikya — Wed, 14 Dec 2022 10:53:23 +0000

We have been conducting a research on fatigue properties of aluminium materials as undergrad level. We have to design an experimental design and decide how much force we have to use in the experiments. However, we are not sure what fatigue life method stress or strain life method we have to use. Is there any specific difference in between (I am sure there is ) but can we use them instead?

Recommendation for helical gear contact

soheyl — Mon, 12 Dec 2022 14:16:41 +0000

Hi
I want to model contact between helical gear. But i don’t know which kind of contact and solver should use.
Do you have any resources?

What is the exact difference between having fixed connection or remote displacement boundary condition for bolted connections?
