Multiscale Modeling of Polymeric Systems for Time-Dependent Nonlinear Properties

Dear Colleagues,

Polymeric systems exhibit macroscopic time-dependent properties, which are important in many applications such as biomedical engineering (drug delivery, tissue culture), rubber industries (automobile tires, seals/gaskets in the oil and gas industry), and soft electronics. Modeling of strain-rate dependent elasticity, hyperelasticity, hysteresis, stress relaxation, and creep behavior at the materials level is required for finite element analysis at the coupon level for designing and optimization. Different models are fitted with experimental data to determine material constants for constitutive modeling and finite element analysis. Discovering new materials through this trial-and-error method is time-consuming. A multiscale modeling technique such as bridging molecular dynamic (MD) simulations with constitutive models facilitates the discovery of new materials. However, as time and length scales are different between molecular and continuum levels, a bridging technique is required between these two levels. This Special Issue welcomes any bridging techniques, not limited to MD simulations; however, the prediction of nonlinear time-dependent properties is expected.

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-anonymized peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Polymers 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 2700 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.
