The aim of the present work is to present an efficient numerical tool for the simulation of the behavior of 3D assemblies of structures with contact and friction when strong structural modifications occur. The paper focuses on the effects of missing connection elements (screws, bolts, rivets, . . . ) on the behavior of the assembly. A fast and efficient domain decomposition strategy for predict...

In this study, a concept and design of self-powered sensor that utilizes triboelectric effect to evaluate the condition tensile bolted joints was proposed. Based on fact charge yields electrostatic voltage induced by separation contacting rough surfaces, proposed is film-shaped made inexpensive materials being installed between objects be fastened. The principle it detects microscale relative m...
