“Explain how the work of [Energy absorption in lattice structures in dynamics
] has enhanced our understanding of Structural Engineering with respect to the work that preceded it, and how this research should be developed further in the future.”

Nowadays, cellular materials are well-known in the world, however, the relationship between dynamic load and the deformation of the lattice structure is less well-studied. Actually, lattice structures can help engineer to produce macro-scale material properties more easier. The research “Energy absorption in lattice structures in dynamics” was focusing on characterising the quasi-static and the dynamic load-deformation behaviour of lattice samples. It’s aim is to investigate failure process and stress–strain

However, lattice structures is relatively less well-known comparing with cellular materials, especially under transient dynamic loading condition. Therefore, having a look on extra reading is necessary before doing research. To find out how this paper is built on previous knowledge, according to the introduction of the article, the first background knowledge is the properties of lattices structure. In the reference list of the article, there is a article which is called “The properties of foams and lattices” [1], it gave a clear introduction of three classes which influence cellular properties, such as the properties of the solid of which the foam is made, the topology and shape of the cell edges and faces and the relative density. Moreover, in the section of “Cellular or ‘lattice’ materials”, it briefly explained what is the structure difference between cellular and lattice material. Therefore, it gave an idea for the research purpose that stiffness and strength of the lattice structure may affected by rate of …show more content…
But why do the structural engineers would interested on the topic of lattice structure? I had read the histories of the skyscraper development, and I found that the steel-skeleton frame design were quite famous in the past, which is similar to lattice structure. [5]One of the example of skyscraper is called Lincoln Building, designed by an architect named Bradford Gilbert in New York city in 1888. There was a limitation that the building is exceptionally narrow plot of land, which directly limited the stories of the building. However, Bradford Gilbert decided to build with a steel-skeleton frame, which was a new design idea and most of the people disagreed with him. Fortunately, he made a model eventually which proved the design is work. The main concept of the design structure is the steel-skeleton frame supported the weight of the building and kept the walls from being thick. As a result of the successful design, the Lincoln Building is still standing up right on the New York City. Therefore, in my point of views, developing and researching the lattice structure in advance which may help the development of the building design in the
