Computer Methods and Experimental Testing for Advanced Structural Materials

Dear Colleagues,

Recent trends in engineering research are seeing diverse computer methods being applied for structural simulations involving advanced materials that are usually subjected to nonlinear deformation. In these problems, the selection of the appropriate constitutive model for describing the material’s mechanical response is crucial, which has to be supported by a robust computational framework (e.g., finite element method, boundary element method or meshless methods) in order to yield reliable simulated results both at the material point and at the overall structural scale. These methods are being applied in vast engineering and scientific branches, modelling a large diversity of materials, ranging from bio-materials, eco-materials, composites, textiles, glass, timber, paperboard to more commonly used materials such as metals, ceramics or concrete.

The reliability of these simulations depends to a large extent on the accuracy of the parameters entered into the governing equations of the constitutive models selected. The calibration of these parameters is traditionally carried out based on data collected from the experiments; these data can be destructive, quasi-non-destructive or completely non-destructive. Inverse analyses provide significant help when transitioning from experimentally measured quantities to the targeted parameters. A similar methodology, with only marginal modifications, can be successfully applied in the diagnostic analysis of aged or possibly damaged structural materials. Computer methods employed in the outlined problems of parameter identification may take advantage of novel techniques such as reduced order models, evolutionary algorithms and artificial neural networks.

This Special Issue of Materials is devoted to the application of some of the abovementioned methods combined with experimental techniques in diverse applications, including (but not limited to) aeronautical, biomechanical, civil and mechanical engineering.

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 250 words) can be sent to the Editorial Office for assessment.

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.
