“…Among many advantages of the DIC system, one can indicate a possibility of data presentation as a function of time either under loading (Figs. 12,13,15) or unloading (Figs. 15d,16,17).…”

“…It is achieved due to elimination of the repeating redundant calculations. In typical DIC approach a speckle pattern is digitalized by means of the measurement frames having rectangular or square shapes, that are used for calculation of a displacement/strain full-field distribution in 2D or 3D coordinate systems 5 , 6 , 8 , 13 without collecting other data such as displacement, velocity, and acceleration versus time at a selected point. Such approach reflects material behaviour for a chosen zones of different dimensions represented by measurement frame features.…”

“…It enables the efficient strain measurements at micro-and nano-scales using the high-spatial-resolution microscopes 4,12 . Thanks to the fact, that it represents the full-field displacement technique [1][2][3]6,13,14 , it is suitable in many practical aspects related to a time reduction of manufacturing processes, optimization of production, and the quality improvement [15][16][17] . Taking this into account, the following applications should be mentioned: cutting 17,18 , stamping and surfacing 17 .…”

The paper deals with experimental attempts for determination of the mechanical resistance of various components subjected to static loading by analysis of displacement values in a 3D coordinate system using a non-contact testing method. The problem is studied on the basis of results from tests of the wheelchair and SUV’s wheel, supported by means of a PONTOS 5M Digital Image Correlation (DIC) system enabling determination of the patterns deflection at discretised facet measuring zones of an element. The objects tested extend a knowledge on the components’ behaviour under static loading within their loading capacity. Data collected in the experiments are expressed by variations of the resultant vector of deflection in the 3D coordinate system and images under loading and unloading stages as well. The results enabled to indicate the weakest zone in the wheelchair and to express an influence of the foot tire on the rim edge, giving necessary knowledge on the mechanical resistance of tested components. In case of the wheelchair a rear side and axle represent the weakest regions, while for the wheel a rim edge is the most loading sensitive region on the tire guard with respect to safety of the operational process. All data captured by DIC system as a function of time can be directly used for modelling and improving a suitability of the selected components since they can be employed as the limit levels during determination of safety factor. The experimental approach applied to the SUV wheel investigation can be also used as a procedure for wheels of other type vehicles tested either in laboratories of research institutions or technical universities.
