Special Issue Information

Dear Colleagues,

Determining the mechanical properties of metals is one of the main challenges in finite element simulations. Correct material parameters and constitutive models capable of capturing the physical behavior of materials are two essential components for predictive finite element simulations. Furthermore, the predictive modeling of a range of metals undergoing inelastic deformation typically requires a number of advanced hardening and damage functions that lead to validated simulation results. In addition, computational mechanics may include new techniques and approaches, such as phase-field modeling, which can predict the degradation of material parameters due to damage occurrence. The development of such techniques will provide a new feature in the investigation of metallic structures. An assessment of the balance of (reversible) strain energy and dissipated energy in the material can improve the simulation quality of the material undergoing cyclic loading.

In this Special Issue, we welcome articles that cover new and improved computational techniques which will either provide a breakthrough or solve challenges associated with the finite element simulation of metallic structures. Equally, advanced techniques and methods required for material model characterization are strongly desirable topics covered in this Special Issue.

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.

In this work, Ti-10V-2Fe-3Al alloy was selected as the test material, and the shot peening process of a CoCrFeNiAlx system high-entropy alloy was simulated based on effective test conditions, and the effects of dry shot peening and wet shot peening on the surface properties were determined. Preliminary simulation results the surface of the test sample display a clear plastic deformation state that gradually diminishes and shifts towards the outermost layer. The stress transfer of the test sample gradually decreases, showing a gradient change, and the twin density also shows a random sample change. Then, the high-entropy alloy shot peening process was optimized, and the best process parameters were determined by analyzing the microhardness data, depth of action layer, and surface state. It was found that after wet shot peening, a new characteristic peak is generated, and with the increase in the size of the shot, its overall kinetic energy becomes increasingly higher, the strain energy of the material surface becomes increasingly higher, and the grain refinement is relatively high. This work provides a new approach to investigating the issues that are present during the shot peening process of CoCrFeNiAlx system high-entropy alloys. Full article
