Special Issue Information

Dear Colleagues,

Structural design in any engineering field is led by iterative optimization processes that traditionally involve operational experience, and at the same time rely on the mathematical behavior of structural theories. In recent years, the characterization and analysis of advanced materials has become fundamental for predicting structural behavior. This is mainly due to the fact that composites and lattice structures are spreading more and more in the industry, pushing researchers towards analyzing and modeling the anisotropic and nonlocal behaviors, as well as the multi-fields, of materials and structures.

The present Special Issue focuses on two main aspects: first, the material, with its design and characterization; second, the structure, with its modelling and solution. As far as materials are concerned, lattice, anisotropic, nonlocal and multi-physics behaviors are considered. On the structures side, the Special Issue aims to attract contributions on the topics of multi-scale modeling, 3D-printed components and computer-aided structural engineering.

The guest editors of this Special Issue hope to attract and obtain the contributions of engineers, mathematicians and material scientists, among others, allowing for creating a multidisciplinary collection of innovative works and stimulating further discussions on these ground-breaking topics. Participants of the "1st International Conference on Computations for Science and Engineering" are encouraged submit their extended conference papers to this Special Issue.

The prediction and control of the transformation of void structures with high-temperature processing is a critical area in many engineering applications. In this work, focused on the void shape evolution of silicon, a novel algebraic model for the calculation of final equilibrium structures from initial void cylindrical trenches, driven by surface diffusion, is introduced. This algebraic model provides a simple and fast way to calculate expressions to predict the final geometrical characteristics, based on linear perturbation analysis. The obtained results are similar to most compared literature data, especially, to those in which a final transformation is reached. Additionally, the model can be applied in any materials affected by the surface diffusion. With such a model, the calculation of void structure design points is greatly simplified not only in the semiconductors field but in other engineering fields where surface diffusion phenomenon is studied.

In this work, the response of a ship rolling in regular beam waves is studied. The model is one degree of freedom model for nonlinear ship dynamics. The model consists of the terms containing inertia, damping, restoring forces, and external forces. The asymptotic perturbation method is used to study the primary resonance phenomena. The effects of various parameters are studied on the stability of steady states. It is shown that the variation of bifurcation parameters affects the bending of the bifurcation curve. The slope stability theorems are also presented. Full article

Structural reliability and structural robustness, from different research fields, are usually employed for the evaluative analysis of building and civil engineering structures. Structural reliability has been widely used for structural analysis and optimization design, while structural robustness is still in rapid development. Several dimensionless evaluation indexes have been defined for structural robustness so far, such as the structural reliability-based redundancy index. However, these different evaluation indexes are usually based on subjective definitions, and they are also difficult to put into engineering practice. The mathematical relational model between structural reliability and structural robustness has not been established yet. This paper is a quantitative study, focusing on the mathematical relation between structural reliability and structural robustness so as to further develop the theory of structural robustness. A strain energy evaluation index for structural robustness is introduced firstly by considering the energy principle. The mathematical relation model of structural reliability and structural robustness is then derived followed by a further comparative study on sensitivity, structural damage, and random variation factor. A cantilever beam and a truss beam are also presented as two case studies. In this study, a parabolic curve mathematical model between structural reliability and structural robustness is established. A significant variation trend for their sensitivities is also observed. The complex interaction mechanism of the joint effect of structural damage and random variation factor is also reflected. With consideration of the variation trend of the structural reliability index that is affected by different degrees of structural damage (mild impairment, moderate impairment, and severe impairment), a three-stage framework for structural life-cycle maintenance management is also proposed. This study can help us gain a better understanding of structural robustness and structural reliability. Some practical references are also provided for the better decision-making of maintenance and management departments. Full article
