Ultrasonic deicing is a new method of deicing. This paper analyzed and designed a kind of ultrasonic deicing acoustic system, then simulated it with the ANSYS, which is a kind of finite element simulation computer software used to do finite element simulation work. The results indicate that the frequency and mechanical properties of the acoustic system meet the expectant demand.

This paper presents aspects of a simulation based on multi-point die optimization sheet metal deformation using for types of materials: titanium grade 1, aluminium 2024, carbon steel 1010 and 1137. Due to processing methods of the sheet metal appeared, multi-point deformation is a very interesting process industry. For the finite element simulation of sheets metal using multi-point die was chosen Deform 3D software. Simulations were performed for four types of materials used in the construction industry. With the development of computer software, specialized programs appeared on the market forming process simulation, for determining the stresses and strains of the deformed material, the distribution of temperature field, how the material is flowing, the final form of the product, etc. Modeling and numerical simulation of deformation processes can be viewed at any time of their deployment, which allows rethinking solutions for problems arising in the process. Also by this method of finite element simulation can be optimized in the design engineering processes and tools.

Si Content

In this work, Si-doped DLC films were deposited on stainless steel (316SS) and polycarbonate (PC) substrates by RF-PACVD in gas mixtures of SiH4+CH4, with 2, 5 and 10 vol.% SiH4. The increase of the Si content in the films led to a progressive drop in the hardness from 30 GPa down to 23 GPa whereas the elastic modulus increased from 124 GPa up to 146 GPa, as measured in the SS coated substrates. In the case of coated PC samples pop-in was observed in the loading curve which was interpreted by finite element simulation and nanoscratching techniques.
