Special Issue Information

Dear Colleagues,

The study of solids and structures is a field of science and engineering dedicated to many aspects, from the most classical problems of structural analysis to solids mechanics. All of these aspects interact with each other, including stress and strain analysis, fracturing, fatigue, flow, wave propagation, heat transfer, thermal effects, optimal design strategies, structural topologies, numerical techniques, vibrations, and general material properties.

The study of solid and structure mechanics is a very active field of research due to the search for challenges and continually innovative solutions. The study of structural behavior, as well as the characterization of new materials being applied in different areas and engineering solutions, bring this area, as always, up to date with new and future trends.

The goal of this Special Issue, “Computational Mechanics of Solids and Structures”, is to bring together the most recent developments and challenges in this field, contributing to strengthening the knowledge of many researchers around the world.

The spectrum of contributions to this Special Issue will provide an exceptional understanding and a complete basis for future research in the study of solids and structures.

This Special Issue is intended to contain contributions based on experimental, theoretical, or computational approaches and their interactions. An important feature will be the interdisciplinarity between work produced by researchers from different areas, including mechanical engineering, civil engineering, thermal engineering, and material engineering.

This Special Issue aims to discuss all relevant aspects, giving a clear and complete overview of the methods applied in new solutions. New trends will be discussed, as will recent developments and solutions that are still under investigation.

Submissions consisting of original articles on the following topics are welcome, though this list is not exhaustive:

  • Structural analysis;
  • Solids and mechanics;
  • Thermal analysis;
  • Finite Element Modeling (FEM);
  • Computational analysis.

This research presents a novel approach to modeling fracture propagation using a discrete lattice element model with embedded strong discontinuities. The focus is on enhancing the linear elastic response within the model followed by propagation of fractures until total failure. To achieve this, a generalized beam lattice element with an embedded strong discontinuity based on the kinematics of a rigid-body spring model is formulated. The linear elastic regime is refined by correcting the stress tensor at nodes within the domain based on the internal forces present in lattice elements, which is achieved by introducing fictitious forces into the standard internal force vectors to predict the right elastic response of the model related to Poisson’s effect. Upon initiation of the first fractures, the procedure for the computation of the fictitious stress tensor is terminated, and the embedded strong discontinuities are activated in the lattice elements for obtaining an objective fracture and failure response. This transition ensures a shift from the elastic phase to the fracture propagation phase, enhancing the predictive capabilities in capturing the full fracture processes. Full article
