The purpose of this paper is to explain why the standard continuum theory fails to properly describe certain mechanical phenomena and how the description can be improved by enrichments that incorporate the influence of gradients or weighted spatial averag... see more

The objective of the paper is to provide an overview of nonlocal formulations for models of elastic solids. The author presents the physical foundations for nonlocal theories of continuum mechanics, followed by various analytical and numerical techniques.... see more

We survey new extensions of continuum mechanics incorporating spontaneous violations of the Second Law (SL), which involve the viscous flow and heat conduction. First, following an account of the Fluctuation Theorem (FT) of statistical mechanics that gene... see more

Introdution. Viruses are a large group of pathogens that have been identified to infect animals, plants, bacteria and even other viruses. The 2019 novel coronavirus SARS-CoV-2 remains a constant threat to the human population. Viruses are biological objec... see more

In this work, non-linear analyses of reinforced concrete plates are performed by using a BEM formulation, based on Kirchhoff’s theory, which has already proved to be a robust technique to deal with plate problems. The non-linear behavior of concrete is mo... see more

The necessity of computational tools to predict the long-term behavior of bone implants and prosthetic devices in orthopedics, has a tremendous importance, considering population aging as a world wide problem. However, specifically in the hip prosthesis r... see more

A brief review of some models of phase transitions within the continuum mechanics is presented. A special study is directed to the phenomena of superconductivity, ferromagnetism, shape memory alloys and the behavior of a binary mixture using Cahn- Hilliar... see more

TOPOLOGY OPTIMIZATION IS A WELL-SUITED METHOD TO ESTABLISH THE BEST MATERIAL DISTRIBUTION INSIDE AN ANALYSIS DOMAIN. IT IS COMMON TO OBSERVE SOME NUMERICAL INSTABILITIES IN ITS GRADIENT-BASED VERSION, SUCH AS THE CHECKERBOARD PATTERN, MESH DEPENDENCE, AND... see more

The performance of structures is of fundamental importance within the structural design, however, the structure response when subjected to loading is a function of several variables. Structures are designed to meet ruin safety criteria and meet service co... see more
