Special Issue Information
Dear Colleagues,
The material property governing fracture resistance due to the propagation of a crack is called fracture toughness. Since most manufactured parts contain defects or microcracks, induced during forming or inherent to material production, fracture toughness is a relevant property to assess their performance. It can be readily measured following well-established standard procedures, which is straightforward for brittle and low ductile materials but can be more challenging for metals and alloys with marked elastoplastic behavior. The measure of fracture toughness is also challenging for ‘thin’ sheets or plates, because the stress/strain conditions affect the property values, and thickness should be considered when characterizing thin-walled structures. New experimental approaches to measure fracture toughness are welcomed to better understand the fracture resistance of engineering materials.
Interest in fracture toughness is growing in new industrial sectors, such as automotive and lightweight construction, where the increasing use of very high-strength alloys is bringing new problems associated with the higher cracking sensitivity of such high-strength materials compared to the former more ductile material solutions. Proper measure of fracture toughness of high strength materials will also allow the development of new alloys with enhanced fracture resistance.
This Special Issue is devoted to papers addressing new approaches to measure fracture toughness in metals and alloys, and their application to understand material behavior during forming or the use of fracture toughness to predict part performance.

Manuscript Submission Information
Manuscripts should be submitted online at www.mdpi.com by registering and logging in to this website. Once you are registered, click here to go to the submission form. Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.
Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Journal of Manufacturing and Materials Processing is an international peer-reviewed open access semimonthly journal published by MDPI.
Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 1800 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
