New Stress/Dynamics Analysis Engineer - Searching for a Good Textbook for Structural Dynamics 5

[hunter872]

Hey everybody,

I recently started my engineering career as a stress/dynamics analyst in the aerospace industry. Although I have a lot to learn, I feel as though I have a pretty good foundation as far as static stress/structural analysis is concerned.

BUT I have almost no background in structural dynamics. I'm trying to find a recommendation for a textbook that would cover the following topics: shock, vibration, dynamic loading, and the corresponding stress analysis methods for components under such dynamic loading conditions. I didn't learn any of this stuff in school. I did take a basic undergraduate dynamics course, but it was limited to applying Newton's Laws of Motion to rigid bodies. I'm trying to find a textbook that explains the theory, like you would learn in school, but is also a practical resource for solving problems in the industry. Shigley's Machine Design is a good example of something that I think accomplishes the theoretical & practical mix I'm looking for (with regards to static stress). I want to learn this stuff well, because I plan on using it for the next couple decades.

I would guess that something tailored to the aerospace industry, as opposed to civil engineering would be preferable, although maybe the theory isn't that different, I don't really know.

Thanks in advance for any recommendations you can provide!

Also, this is my first post on Eng-Tips, so I apologize in advance if I posted this in the wrong place or made any other errors.

have you looked into the texts used by, say, MIT's opencourseware site ? or many others online (UKansas, etc) or texts used by study courses you can find.

I understand wanting to get a recommendation before shelling out the bucks, but I'd be happier if you asked which of these books would you recommend, list some promising hits, and include "another"
show us you've done some of your own research.

"shock, vibration, dynamic loading, and the corresponding stress analysis methods"

For shock and vibration

https://www.amazon.com.au/Harris-Vibration-Handbook-McGraw-Hill-Handbooks-ebook/dp/B002XLYOKG

is widely used in automotive.

Depending on what you mean by dynamic loading that is probably covered as well.

So far as stress analysis goes you'll be using FEA.

Cheers

I will suggest three books for young engineers..you will see a lot of worked examples at the book = Shock, Impact and Explosion. (by M.Y.H. Bangash )

-Vibration and Shock Handbook (By Clarence W. De silva )

-Harris' Shock and Vibration Handbook ( by Allan G. Pierrsol ,Thomas L. Paez )

-Shock, Impact and Explosion. (by Prof. Dr. M.Y.H. Bangash, Emeritus Professor of Aerospace)

Hi Hunter,
Welcome to Eng-Tips.
It's not precisely what you're asking for, but I'm working my way through Daniel Inman's Engineering Vibration textbook right now, just to brush up on the subject.

This book really appeals to me because it also coaches you through the development of MatLab/MathCAD calculations at the same time. I'm already a proficient user of Mathcad, and have a copy for home use. At the end of chapter, I end up with a dozen or so calculations in ML/MC that I can use later for real-life calculations. I'm having a bit of fun after finishing the problems, and "extending" the calculations to see what else I can work out based on the over-simplified example.

In my 20-year career, I've reaped big rewards from being able to re-use calculations done in the past. Carefully annotated, that they can be picked up again a few years later with minimal loss of familiarity. I can quickly jump into a problem similar to one I solved before. Using the calculations BEFORE the design is finished allows optimization, and avoidance of trouble early in the design.

First of all, thanks for the responses everyone! All of them were very helpful, and I'm looking forward to using and contributing to this forum in the future.

rb1957: I think you may have misunderstood the intent of my post. I probably should have made my intention more clear. For what it's worth, I am doing my own research in parallel to this post. But, I wasn't asking or expecting anyone to do research for me. I was requesting recommendations that people might have 'off-the-top-of-their-head', based on professional experience. I will take your advice about researching the texts that university courses are using, I hadn't thought about that. Would you be concerned with academic recommendations not being as applicable to industry use, or am I over-thinking this? Thanks for your input!

SWComposites & HTURKAK: I've been a little worried about buying something that is a "handbook" or formula book because I'm worried that I will miss out on important theory that I have never learned in school, and need to know to correctly select/apply the formulas. Do you think that is a valid concern, or am I over-thinking this? Thanks for your input!

As a general question, would y'all be worried about using a civil engineering oriented shock/vibe/dynamics textbook for aerospace work? I'm asking because a lot of the textbooks I found for "structural dynamics" were oriented to civil engineering or written by civil engineers. Although they often advertise their use for other industries, I was concerned that there might be enough differences in the types of loading to make civil engineering sources not applicable to aerospace.

Thanks again everyone!

NP, there are way too many posts from people without having done the easy initial searching. You asked about texts for analysis … academic sources are just as applicable as industry. Sure, academic texts will be more "academic" ! (more "sciencey", less practical) but should certainly describe what dynamic analysis is and how to do it. How to apply it would be more the field of industry texts, but these'll really be focused on production aircraft, so a lot of the hard data will be proprietary. Possibly the best compromise is a grad level course at maybe Cranfield where they use a problem defined plane and get you to do the specific analysis on it.
