Since the invention of the first UAV’s, different industries realized it’s capabilities and potential uses. Drones and UAV’s are part of our everyday life and their development has seen an unprecedented speed due to their multiple applications, from scientific research to military applications. When we talk about UAV’s we also talk about composite materials. Today’s drones and UAV’s are using almost exclusively carbon fiber, glass fiber and 3D printed materials. This paper presents the development and testing of fiber carbon materials along with a future concept of an UAV. In the end of this paper the results of testing the materials are presented.

“…Many of them use the finite element method (FEM) in combination with probabilistic methods. Probabilistic calculations of the durability of concrete structures influenced by the aggressive substances play an important role [22][23][24]. The probabilistic FEM solution is quite common for the assessment of static properties of civil engineering structures [25][26][27]; however, it is not very common to extend it to the durability area, and therefore many questions remain open in this field of science.…”

Sensitivity Analysis of Stochastic Calculation of SCC Regarding Aggressive Environment

Probabilistic procedures considering the durability with respect to corrosion of reinforcement caused by aggressive substances are widely applied; however, they are based on narrow assumptions. The aspects need to be evaluated both in terms of the search for suitable application of the various experimental results and in terms of their impact on the result of the stochastic assessment itself. In this article, sensitivity analysis was used as an ideal tool to prove how input parameters affect the results of the evaluation, with consideration of different types of concrete (ordinary or self-compacting with and without fibres). These concretes may be used in aggressive environments, as an industrial floor or as a part of the load-bearing bridge structure. An example of a reinforced concrete bridge deck was selected as the solved structure. The results show that in the case of a classic evaluation, a larger amount of fibre reports a lower resistance of concrete, which contradicts the assumptions. The sensitivity analysis then shows that self-compacting concrete is more sensitive to the values of the diffusion coefficient, and with the consideration of fibres, the effect is even greater.
