How is this relevant? My goal is to improve the methods my organization uses currently. The effect of water is ignored currently for design/analysis. I am hoping that the experts here can point to some equations and/or literature for further study.
It probably will, there’s no testing planned. But, we’re hoping to improve simulation by accounting for surrounding fluid. Is it possible to write kinematic or energy/momentum equations for such collision in air? How to consider effect of fluid?
I am asking about the case in air because all the work done to date ignores effects of surrounding water. Also, to understand the formulations to be used in air and then how to modify for surrounding water. No testing is intended.
Past work assumes impactor(s) to be idealized rigid body with a...
Yes, this is a very clear qualitative description of what may be observed.
How will the absence of water affect the results (collision in air) or "damage"? For collision in water, will the ambient hydrostatic (head) pressure change the results or "damage"? For context, many of my co-workers...
Not a sharp point. The impactor will be 90 mm dia cylinder with a rounded (say, hemispherical) impacting surface, approaching perpendicular to the plate at its geometrical center. At the instant of the impact, the kinetic energy is 5000 J per previous reply.
This would be narrows the situation...
Assume a 1 m x 1 m plate, about 10 mm thick, surrounded by water on all sides. No pressure vessels are involved in the collision. The plate is an idealized target, one can think of it being welded on all sides to a more rigid structure made of I-beams.
The behavior of impactor before collision...
Thank you. The speeds are low, but mass can be quite large. The energy can vary from roughly 500 J to 5700 J. In any case, a simulation is required, but there are so many assumptions involved that it is tough to assess if the actual physics is captured or not. Being surrounded by water should...
I did not edit the question. I have added the info that DaveC426913 asked for.
If someone asks for more info, what is the protocol to provide that info?
Imagine there is a square plate fixed at the edge on all sides, it is impacted by a body with a pre-determined kinetic energy. Now assume that this plate is submerged in water and impacted by an identical body with the same amount of kinetic energy. Will the results be different? How to...
