The Shape-Structure Relation For The Light Construction Membrane Type

Abstract

In the case of light structures membrane type the form is confused with the structure and vice versa. Thus the analysis process, non-linear type, the one for form finding is also a means of optimizing these structures. To respect the natural principle of minimum it is advisable that the structure’s shape is similar to the minimum surface area. The numerical problem solving is based on using finite elements with constant strain of soap film. Based on these considerations, the paper presents aspects of determining the shape of the membrane structure using finite elements of soap film.

Development of Large Concrete Object Geometrical Model Based on Terrestrial Laser Scanning

Abstract

The paper presents control periodic measurements of movements and survey of concrete dam on Dunajec River in Rożnów, Poland. Topographical survey was conducted using laser scanning technique. The goal of survey was data collection and creation of a geometrical model. Acquired cross- and horizontal sections were utilised to create a numerical model of object behaviour at various load depending of changing level of water in reservoir. Modelling was accomplished using finite elements technique. During the project an assessment was conducted to terrestrial laser scanning techniques for such type of research of large hydrotechnical objects such as gravitational water dams. Developed model can be used to define deformations and displacement prognosis.

Simulation of the Process of Metal Hardness Measurement by the Rockwell Method

Abstract

The article presents a simulation of metal hardness determination by the Rockwell method. The authors describe a physical model of an indenter and the examined sample built by means of the Nastran FX 2010 program using the finite elements method. The modelling included subsequent stages of indenter loads that follow the procedure used in the method. The verifying calculations were made for the results of C45 steel hardness of approx. 20 HRC. Two methods of hardness measurements were analyzed. A diamond cone was used as an indenting tool in one method, a steel ball in the other. As a result of calculations, spatial maps of elastic and plastic strains and stresses were obtained throughout the process. The hardness results obtained from computer simulations and those from experiments involving C45 steel are similar.
