Special Issue Information
Dear Colleagues,
The interest on structures jointed by spot welds is strong especially in automotive and railways applications, where structures may contain several thousands of spot welds. These spot welds are subjected to complex multiaxial loads both under service or crash conditions. The stress field close to the spot region is quite complex, mostly due to geometrical irregularities and several local effects at the edge of the spot weld. Moreover, structural behaviour and local stiffness evaluation of spot welds show some complexity, due to the difficulties in accurate modelling, using finite element models, the region close to each spot weld, featuring local high stress/strain, associated with very high stress/strain gradients. Furthermore, it is necessary to use models that involve only a few degrees of freedom, since real structures usually contain several spot welds: modelling each of them with accurate and complex FE models would require a major computational effort.
In this Special Issue, modern trends of spot welds modelling concerning any phenomena, from fatigue to plastic collapse, using theoretical, experimental or numerical approaches, are highlighted and discussed.
It is my pleasure to invite you to submit a manuscript for this Special Issue. Full papers, communications, and reviews are all welcome.

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. Materials 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 2600 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.
