The chemical, physical and biological contaminants that are described in many impact studies in aquatic environments show that these can come from a variety of sources, but mainly from urban anthropogenic activities. These contaminants can accumulate

A process to efficiently design composite wing boxes is presented. It uses analytical and semi-empirical equations for failure modes such as material strength, plate buckling, stiffener column buckling and stiffener flange or web crippling. Laminate

This paper proposes a numerical approach to estimate the dynamic behavior of a typical aeronautical aluminum box-beam structure liable to buckling. The methodology is based on a nonlinear finite element model and an experimental modal analysis proced

Uma caixa para flexo-torção, equipada com múltiplas longarinas - sem reforçadores ou nervuras - é um conceito propício à tecnologia de compósitos. A integração de almas e revestimentos possibilita um único ciclo de cura em processos à bas
