“…[38][39][40][41] The application of this optical method in the correlation of digital images requires a minimum of one camera, a light source and an algorithm that will enable the correlation of digital images obtained as a result of recording. 42 The method is based on monitoring the displacement of points located on the sample surface (Figure 7). Result is obtained by comparing the positions of the measuring points in the undeformed and deformed state, which is further calculated on a computer.…”

Martial arts and fight sports are mostly based on exchanging the punches and kicks that often result with injuries of face, skull bones, and neck vertebrae. One of possibilities to reduce number of injuries in athletes who deal with martial arts is development of new materials and improvement of designs for helmets used in sport fights. In order to experimentally analyze impact forces and simulate conditions during different fight punches mechanical installment was made. Aramis system is used to measure the displacement fields and the distribution of deformations which occur on the neck over the entire analyzed area based on the correlation of digital images. On this manner better understanding of behavior of both materials and structures during the action of the impact forces and loading is obtained. This information can further be used in researches related to the development of helmets used in martial arts which would influence reduction of values of neck deformations in athletes.

“…Also, numerical methods enable results of full covered stress-strain field that can be easily verified by the data obtained from experiment. This 3D DIC method has high accuracy (up to 1 μm) and it has been used in variety of cases so far: different material testing, structure testing, model verification, fracture mechanism [24][25][26][27][28][29][30][31][32][33][34][35][36][37].…”

Boilers are one of the most used units for both heat generation plants and industry systems. Their operation is subjected to different working loads and maintenance requirements. Exploitation experience points out critical boiler zones where failures and break downs typically occur. This paper analyzes critical zones in hot water fire-tube boiler. Experimental procedure was performed on the model of this type of boilers and its critical element. The tube plate of hot water boiler was identified as the most critical one. Experimental analysis and numerical model verification were performed using Aramis system based on 3D Digital Image Correlation method. Numerical analysis was done in Ansys Software Package and verification of results was done based on measurements obtained by strain gauges and local measurements performed by the Aramis system. Stress-strain analysis indicates the critical zones of boiler tube plate. The character of change parameters such as strain and stress occurring in the critical zones can be verified both by experimental and numerical data. The paper presents a novel approach in experimental and numerical analyses that can be conducted in similar units and used for existing unit optimization, as well as for new product testing on different loads and provide opportunity for further development and improvement for practical industrial application.
