Special Issue "Constitutive Modeling of Welded Joints"

Dear Colleagues,

Constitutive modeling as a mathematical description of how materials respond to various loadings is the most intensely researched field because of its complexity and the importance of accurate constitutive models for practical engineering problems. Welding is a very complex thermomechanical process which involves four disciplines: continuum mechanics, heat transfer, materials sciences and production engineering. The mathematical modeling of welding requires simplifications and experimental verifications related to metallurgical and fracture toughness tests of weld joints. The welded joints fabricated by the fusion welding or solid-state welding process can consist of the following major regions: the base material, the heat-affected zone (HAZ), the thermomechanically affected zone (TMAZ) and the weld metal (or weld zone). Depending on the type of material that is being welded, the weld metal (or weld zone), TMAZ or HAZ usually shows the lowest strength. Therefore, specific constitutive models are crucial for predicting the behavior of welded joints. Integrating the thermomechanical behavior of materials into simulations of welding processes plays a major role in the understanding and prediction of important aspects such as residual stresses, plastic distortions and metallurgical transformations in welded engineering structures. In this Special Issue, we welcome articles that focus on the constitutive modeling of welded joints. Potential topics include, but are not limited to, the following:

• Fusion welding;
• Solid-state welding;
• Constitutive models;
• Plasticity;
• Thermomechanical behavior;
• Finite element method;
• Finite difference method;
• Finite volume method;
• Multiscale modeling;
• Phase-field modeling.

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. Metals is an international peer-reviewed open access monthly 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 2000 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.
