Small earthfill dams, without permanent water storage, are simple operation constructions without any outlet operation or control systems, and which provide water storage in flood wave periods. From the seepage point of view, these simple constructions have a specific complex behavior. Even if generally the body of the dam can be considered to be homogeneous, infiltration through partially saturated materials is unsteady. The water level rapidly increases from the minimum to the maximum level as the water storage volume is relatively low.
The main objective of this paper is to show the advantages of advanced manufacturing, such as high speed machining (HSM), for the active plates of injection molds. The goal of the experiment is to push the machine and the tools to the limit without reducing the surface quality of the manufactured part. The parts that are machined in this experiment are the active components of bucket injection mold. The mold core and nest is composed of several plates that have to form a whole when mounted together.

The textile reinforced concrete is a material with increased mechanical properties that can allow the production of lighter structural elements. The alkali-resistant textile reinforcement is not affected by corrosion. A structural facade panel and a light pole were modeled in order to study their behavior in the case of wind pressure. The developed numerical simulations were calibrated according to available data from the literature. These simulations revealed information potentially useful in the planning of further experimental tests.
