Hi everyone, bit of a debate going on amongst some mechanicals at my company and I thought I'd fish for some insight online. With regards to the natural frequency of a spring (both ends fixed), I've encountered a company design guide that suggests a spring will resonate longitudinally at...
Per Ashby and Jones, the crack growth rate is described by:
da/dN = A(deltaK)^m
and goes on to say that A and m are material constants. Has anyone turned up A, m data on any web resources for Inconel alloys? I've seen a few journal article abstracts that make reference to them, but nothing...
Hi all,
I'm having a tough time turning up any literature pertaining to the subject line problem. Perhaps this is predominantly due to my newness to the field of vibration analysis and the concurrent lack of keyword insight for searches.
Spring material: 302 SS, spring temper (AMS5688)...
I appreciate any help I could get with this problem. Basically I am trying to analyze the flow of air through 4 sharp-edged entrance orifices into an annulus then out 12 sharp-edged exit orifices. So it flows in, takes a right turn then travels about an inch then out the bottom orifice. It'd be...
Please help me settle an argument in flow of turbulent water through a coil. I argue that one must account for an increase in the effective length of the coil due to the continuous bend of the pipe as it follows the helical path. In my opinion this effective length increase may be modeled as...
Greetings all,
I could use some help tracking down a extensive chart showing stress concentrations for plates with a central hole for the case of an applied bending moment.
Additionally, any commentary or tips on the problem of designing a padeye to sustain a force applied at an angle to the...
