Special Issue "Crystal Plasticity Modeling and Simulation"

Dear Colleagues,

Crystal plasticity (CP) modeling has emerged as a versatile and powerful tool. It describes the mechanical behavior of polycrystalline materials from the perspective of single-crystal deformation response. By this, the design of novel materials could be accelerated because the microstructure–property relations in crystalline materials are revealed rapidly. In recent years, implementing CP models to the finite element method (FEM) and fast Fourier transform (FFT) provides the visualization of microscale heterogeneous deformation states. CPFEM and CPFFT simulations can serve as effective approaches for micromechanical virtual experiments. In engineering, the CPFEM method is commonly used to predict the fatigue life of aerospace, vessel and nuclear equipment components.

Nowadays, there are three important trends in CP modeling and simulation:

• Considering multiple plastic mechanisms (TWIP, TRIP, GB migration, etc.) to describe the deformation behavior of high entropy alloys and ultra-fine-grained alloys;
• Coupling with phase-field or strain-gradient theory to accurately simulate nonlocal processes, such as crack propagation, twin growth, etc.;
• High-performance multiscale numerical frameworks for modeling multiphysics (heat, force, electricity and magnetism) CP phenomena.

Solving these currently open questions requires substantial effort. A reliable CP simulation can only be performed by having well-established knowledge of crystallography, dislocation theory, continuum mechanics, numerical algorithms and code programming.

This Special Issue is especially dedicated to the latest research providing new insights and practical findings in crystal plasticity modeling and simulation. Potential papers include, but are not limited to, the following subjects:

1. Dislocation mechanism-based crystal plasticity modeling;
2. Coupled phase field-crystal plasticity simulation;
3. Strain gradient crystal plasticity theory;
4. Crystal plasticity simulations for damage, fracture and fatigue;
5. Machine learning approaches in crystal plasticity;
6. Visco-plastic self-consistent (VPSC) crystal plasticity 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. Crystals 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 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.
