ROTARY BENDING TYPE FATIGUE TESTING MACHINE FOR PLASTICS

Rotary-bending fatigue characteristics of medical-grade Nitinol wire.

The rotary bending fatigue properties of medical-grade Nitinol wires were investigated under conditions of 0.5-10% strain amplitudes to a maximum of 10(7) cycles. The results from this study provide insight into the behavior of Nitinol under fully reversed (εmin/εmax=-1) fatigue conditions for three compositions, two surface conditions and three test temperatures. For pseudoelastic conditions t...

Fatigue testing of controlled memory wire nickel-titanium rotary instruments.

INTRODUCTION To improve the fracture resistance of nickel-titanium (NiTi) files, manufacturers have introduced new alloys to manufacture NiTi files and developed new manufacturing processes. This study was aimed to examine the fatigue behavior of NiTi instruments from a novel controlled memory NiTi wire (CM Wire). METHODS Instruments of ProFile, Typhoon (TYP), Typhoon CM (TYP CM), DS-SS025042...

Various Fatigue Testing of Polycrystalline Silicon Microcantilever Beam in Bending

With the vast potential of micro-electro-mechanical systems (MEMS) technology, the reliability is essential for the successful applications of microdevices. Polycrystalline silicon is one of the most often used structural materials in microdevices. Tension testing for fatigue life of this material has been investigated since past years. This paper presents a micro-actuatorbased bending testing ...

A scalarization-based method for multiple part-type scheduling of two-machine robotic systems with non-destructive testing technologies

This paper analyzes the performance of a robotic system with two machines in which machines are configured in a circular layout and produce non-identical parts repetitively. The non-destructive testing (NDT) is performed by a stationary robotic arm located in the center of the circle, or a cluster tool. The robotic arm integrates multiple tasks, mainly the NDT of the part and its transition bet...
