More than 280 trees were uprooted in winching tests monitored by high resolution inclinometers at the base of and a forcemeter mounted line. The dataset comprises growing on different urban forest sites Europe North America mainly consists fifteen widespread tree species. For first time, large number measured non-destructively prior to uprooting failure, as commonly practiced consulting arboris...

stress and residual stress are the main problems in the operating performance of materials. they are the principal causes of material failure and can affect life time of component. however measurement or predictions of them are typically difficult. two common non-destructive methods, x-ray diffraction and ultrasound are not reliable methods for subsurface residual stress measurements and destru...

Residual stress states in engineering structures are determined usually by measuring components of stress tensors with depth below the material surface. There are destructive and non-destructive methods to measure strain tensor components and convert them into stress tensor components by a variety of techniques derived from constitutive (material) equations. In this study, four methods for dete...

In this paper, a non-destructive eddy current test system was designed to evaluate the surface hardness of the carbonitrided steel parts. For this purpose, various samples of the tappet were used after the surface hardening and grinding operations as control samples and, if necessary, were subjected to destructive and non-destructive tests. Microstructural studies were performed with a microsco...

Automation of non-destructive testing (NDT) of engineering components and structures represents one of the strategic objectives of many industries. It enables increases in accuracy, precision and speed of inspection while reducing production time and associated labour costs in contrast to manual inspection. The use of robots can provide additional flexibility and autonomy to automated NDT. Auto...
