I. The High Strain Rate Response Of Hollow Sphere Steel Foam; Ii. The Dynamic Response Of An American Elm Tree, Ignacio Cetrangolo

Masters Theses

PART I

Hollow-sphere (HS) steel foam is a relatively new material whose cellular morphology and material properties qualify it as a metallic foam. This is an innovative foam-like material that exhibits high stiffness paired with low relative densities. Technological advancements in the past few decades have enabled the manufacturing of this material by a sintering process and, as a result, research has begun to accelerate as a multi-school collaboration effort for this particular work. Even though commercialization has been a challenge for metallic foams, it is imperative that researchers continue to prove and promote the advantages of metallic foams despite …

An Automated Approach To Dynamic Site Layout Planning, Duy Huu Nguyen

Masters Theses

Dynamic site layout planning involves determining the optimum location of resources on the construction site. Site layouts are considered dynamic because construction activities and the number and nature of associated resources change as the project progresses. Previous research has focused on the use of several algorithms to address dynamic site layout problems. These efforts do not enable automated tracking of the dynamic context of construction resources, site space and activities. This research presents an automated adaptive component level system capable of generating layouts which are optimized throughout the phases of construction projects. The system involves the integration of building information …

Dynamic Characteristics Of An Frp Deck Bridge, Jing Song

Masters Theses

Fiber reinforced polymer (FRP) deck has some significant advantages compared to concrete deck in use of bridges, such as light self-weight, high stiffness and strength, good durability and easy to install. FRP deck has already been used in some bridge rehabilitation and short span bridges. But for widely used in bridges, FRP deck bridges still need further research. Currently many research efforts focus on the filed tests of FRP deck bridges. Compared to field tests, Finite element analysis also has great advantages, such as low cost and convenient to conduct. Therefore, in this thesis finite element analysis is conducted by …
