Not sure if I'm on the right track here at all.
p=40*10-6*6*10-3*290*109/1=69600 Pa=69.6 kPa
Have you learned about the general form(s) of the Hooke's law relationship for multiaxial loading?sponsoraw said:Chet, looks like I may need a bit more help.
Yes. Nice job. You need to look up the Poisson ratio for the pipe material. They give you the Young's modulus, but not the Poisson ratio?sponsoraw said:Will the hoop strain for a closed-end cylindrical pressure vessel be ε=(p*ri/t*E)*(1-v/2)? How do I get v?
A pressure vessel's strain refers to the deformation or change in shape that occurs when it is subjected to pressure. This can be caused by internal pressure, external forces, or a combination of both.
The strain in a pressure vessel is typically measured using strain gauges, which are sensors that can detect small changes in length or shape. These gauges are attached to the vessel and connected to a data acquisition system that records the measurements.
Several factors can affect the strain in a pressure vessel, including the material properties of the vessel, the type and magnitude of the pressure, the design and construction of the vessel, and the operating conditions such as temperature and vibration.
The strain in a pressure vessel is typically analyzed and evaluated using various engineering and scientific methods, such as finite element analysis, stress analysis, and strain-stress curves. These methods help determine the safety and reliability of the vessel under different operating conditions.
Excessive strain in a pressure vessel can lead to various risks, including structural failure, leaks, and explosions. It can also cause the vessel to become unstable and affect its performance and longevity. Therefore, it is crucial to monitor and maintain the strain within safe limits to ensure the safe operation of the vessel.
