Abstract. The main purpose of paper is presented an innovative approach in the field of infrared thermal imaging and its integration into the area of engineering applications. As the test specimen was selected composite rod with lengthwise composite fibers to each bonded. They have been excitated with ultrasound. For obtain the results was used Lock-in method. Last part of the paper is a description of the results and most appropriate settings of measurement technique for applications with chosen material.

Durability calculations of bearings take in account the distribution of forces on rollers. Calculation of these forces in flexibly supported rings is the aim of the paper. We use simplified finite element (FE) models of bearings, which are integrated into the external geometry. This approach can consider the stiffness of the surrounding structure as well as the clearance of the bearing rings, the misalignment of bearings, shaft deflections, and the forces of crowning rollers. The presented results show an influence of the initial radial interference of the outer ring with housing on the distribution of forces in bearing rollers. As the radial stiffness of the housing is close to the stiffness of the outer ring

The main purpose of this paper is monitoring propagation of plastic area of fatigue crack. There were made notch on specimens and they were cyclically loaded with three-point bending. The record was evaluated after a certain number of loading cycles. The loading force is still constant throughout the measurement time for all specimens. The whole process was recorded using an infrared camera.

In this paper, an effort has been put to analyze the rolling ball bearing using finite element analysis the contact pressure level, stress or displacement behavior of rolling ball bearing. The obtained results were then compared with the analytical results obtained through the methodology of Hertz theory in order to demonstrate an almost identical similarity of results and correct setting up of the given simulation in computational software ANSYS Workbench.
