[Open Access, see DOI] When fiber-reinforced plastic (FRP) components are designed, it is very important to ensure that textiles are formed into complex 3D geometries without folds, and that the reinforcing structure is oriented appropriately. Most research in this context is focused on finite element (FE) forming simulations and the required chara...
Chapter
This article describes the development and the calibration of the photoelastic contactless torque sensor and it also presents the measurement of the starting torque of a disk micro motor, as a function of the rotor angle. Finite element analysis was performed to prove the functionality of the sensor and to determine its required sizes. In order to...

This paper describes the development and the calibration of a photoelastic torque sensor and it presents the measurement of the starting torque of a DC micromotor as a function of the rotor angle. Due to the relatively small torque (<10 mNm) of the DC micromotor, a new type of photoelastic torque sensor or rather a measurement method had to be deve...
Article
This study aimed to explore whether cone beam computer tomography (CBCT) and multi-slice computer tomography (MSCT) can be used to quantify tissue density and to determine if the Hounsfield Unit (HU) scale is applicable. A clinical MSCT and effective energy adjusted photon beam attenuation references were used to compare the gray scale of CBCT im...
Article
During the research, scanning electron microscopy, compression, tensile and frequency analysis were performed on silicone rubbers filled with conductive particles , in order to understand the electrical conduction mechanism. The distribution of the conductive nanoparticles and its relationship with the substrate was examined with scanning electron...
Article
For the simulations of elastic constructions actuated by inner pressure we need for the definition of the material model parameters, the data originating from the biaxial test. The paper reviews the biaxial material testing methods, especially the bubble inflation methods. It contains a short summary of the stress analysis of the rotation ellipsoid...
Article
This study analyzed detailed models of human mandibles at 3 different stages of life with simulation of supra normal chewing forces at static conditions. Finite element analysis (FEA) was used to generate models from cone-beam computerized tomograms (CBCT) of 3 patients aged 12, 20, and 67 years, using numerically calculated material parameters. Es...
Article
Silicone rubber is an essential construction material in food industry, medicine and in some fields of mechanical engineering, because it has good mechanical, electrical, biological and other special properties. One needs to know these material properties in order to develop silicone sensors. We performed several standard measurements for rubber, l...
Article
Silicone rubber is an essential construction material in food industry, medicine and in some fields of mechanical engineering, because it has special mechanical, electrical, biological and other special properties. Over the usage of silicone rubber as structural material, the "intelligent" behaviour is more and more important. In this case the ques...
Article
This paper presents an overview about results of mechanical testing of human tendon. We are dealing with the main function of tendon and touching on typical insurance of tendon and reconstruction of them. Since the material characteristic of tendon and dynamic models of them are not known there was made a lot of uniaxial tension test and based on m...
