Weld Toughness
The purpose of this Bulletin_86 is to provide links to Online Sources.
Toughness is the ability of the weldment to absorb energy in the plastic range.
It is one of the material properties studied by Mechanical Metallurgy.
This is the field of metallurgy dealing with the response of metals to external forces.
In particular, in many engineering applications, it is essential that weldments be capable to sustain impact loads without fracturing.
This capacity is assured by constructions exhibiting adequately high fracture toughness.
The subjects relevant to this property are studied with suitable tests and the results are explained and exposed in books and research papers listed hereafter.
The Online Resources listed in this Bulletin_86 offer a wide range of publications presenting essential knowledge on the above matters.

The references published in this Bulletin_86 are selected to provide useful knowledge to our readers.
Some of the sources are commercial companies, presenting their services or goods together with technical advice.
No endorsement or recommendations of such offers is intended.
Readers should check if such information meets their purposes and needs.
The addresses reported hereafter in this Bulletin_86 were live and correct at the time of their publication.
There is no guarantee that they will always be so, because they are administered by the sources themselves and are under their control.
Note: References to articles or other documents are given here in one of two forms.
If the links are "live" (usually underlined or otherwise highlighted) they are operated with a click of the mouse.
If they are URL's (Uniform Resource Locator), which is the analogue of an address, they begin with "http://..." or "www.".
These are not live and must be copied and pasted entirely into the browser (after having selected them with the mouse or otherwise).
If they are long they may be displayed in two or more lines.
In that case one has to care that the URL be copied completely in a single line without any space, and Enter.
If the information is important to you, you may save the downloaded selected pages in a suitable folder on your Computer for easy reference.
You are welcome to forward this Bulletin_86 Resources page to those of your friends who may profit of this information.
