Books to get knowledge of aerospace metallic materials.. 3

[MCA1983]

Hello all,

Is there any books to refer for aerospace metallic materials.. MMPDS is getting difficult to understand.. any simpler book with MMPDS content ?

Thanks

 

[rb1957]

what are you looking for ? MMPDS has all the data you could want, which is what it supposed to have.

if you're looking for understanding this data, maybe Bruhn, Section B ?

etc

I'd need more details to make a solid recommendation.

Are you looking for a source of material properties and allowables?

Or are you looking for books on aerospace design and strength?

For starters I'd say the classic "Structural Design in Metals" by Williams and Harris is probably dirt cheap on ebay.

Have you read all of the support information in the MMPDS?
I would start there.
The other thing that you need for MMPDS is to understand the statistical methods behind the values.
This varies by each different section of stress values.

Deeeeelux...

The Metallic Materials Properties Development and Standardization (MMPDS) Handbook, is an accepted source for metallic material and fastener system allowables recognized by the Federal Aviation Administration (FAA), all Departments and Agencies of the Department of Defense (DoD), and the National Aeronautics and Space Administration (NASA) within the limitations of the certification requirements of the specific government agency. Some of these limitations are noted below.

MMPDS is light on material physical properties... heavy on authoritative mechanical allowables.

Aerospace Structural Metals Database (ASMD)... WAS: Aerospace Metals Handbooks [ASMH] ...

https://cindasdata.com/products/asmd

... ASMD/ASMH Does deep dives into the physical and manufacturing and mechanical properties of most common aerospace metals. and is also authoritative.[URL unfurl="true"]https://res.cloudinary.com/engineering-com/image/upload/v1698116421/tips/ASMD-AlloySheet_imnuuy.pdf[/url]

Both of these should be available thru well-funded technical libraries... especially companies.

Be wary... next category 'DOWN' is 'informative' data... good generalized data that informs... but may or may NOT have legal 'stature' such as 'authoritative data'... not to be used for design...

Then there is textbook data... intended for training/teaching... and general information... starter info... usually out-of-date when published.

For many alloys there are 'White papers' describing the alloys in great detail... useful and highly informative... but often preliminary and out of date.

Also, many companies publish their own materials data for locally defined/developed alloy variants under their own proprietary [company] specifications. Or publish similar-to data common alloys/industry specifications... but with notable statistical differences for their specific usage.

I'm looking for aerospace design and strength aspect.. I got suggestion to go thru MMPDS for aerospace materials.. but too informative that I'm not looking now.. I need to start with basis and will relate to aerospace parts..

 

[WKTaylor]

MCA1983... metric [SI] or English [In#] data?

Sounds like You may REALLY need to refer to an in-depth design manual/text with embedded materials data/tables for use in 'their design/analysis example/sample problems'... to get the feel for integrating materials data into stress analysis examples.

[MCA1983]

I'm look in SI units..

 

[WKTaylor]

From my library...

You need to use ESDU Metallic Materials Data Handbook [SI units]..

Abstract: The design engineer faces an ever-increasing demand for products with a performance that must be substantiated under stringent conditions of cost and environment. Assuming the basic skill of the designer, no other single factor can contribute more to the economic preparation of a satisfactory, competitive engineering design than ready access to good reliable design data.

Data concerning aerospace structural materials are widely scattered and, when located, are of variable quality and relevance to industrial applications. The task of collecting and evaluating all the relevant data available on a particular material property is time consuming and therefore expensive. Even if such a task is performed it is often found that the customer will wish to view the design, not against some locally derived data, but against what can be demonstrated to be the best data that can be ascertained and which are vouched for by a significant cross-section of the engineering and scientific community concerned with both derivation and application of materials data. Accordingly, this Handbook has been prepared to meet design requirements with regard to aerospace structural metallic materials properties for both the designer and his customer and, by serving the needs of many, accomplishes the task at much lower cost and with a higher reliability than could the individual.

Thanks WKTaylor.. I will go thru ESDU materials..

I don't recall the designation on the handbook behind the MMPDS. There is one that describes all of the methods, limitations, and applications.
You might need to contact Battell Columbous to find out what it is.

...the handbook behind the MMPDS...

"behind" in what way do you mean?
In MMPDS chapter 9 is pretty detailed about methodology behind the results.
The predecessor to MMPDS is Mil-Hdbk-5 (the predecessor to that is ANC-5).
Yes Batelle is the custodian of this data now, under contract to the FAA, but it used to be the US military. They compiled the data from a wide variety of sources; some from airframe OEM's, some universities, some fastener makers, some foundries, some industry associations, etc.

 

[EdStainless]

I haven't looked lately but dose chapt 9 describe the statistical methods used?
There are a specific number of samples required from a minimum number of different heat lots.
Teh statistics are different for the different basis of stress.
Yes, there are some that simply based on specification minimums, but some are much more involved.

Yes, the stats methods are described in MMPDS.
