Fatigue Failure and Damage Analysis of an Anti-roll Bar Subjected to Fatigue Experiments
The available fatigue theories have been examined using simple specimens subjected to bending or tension-compression loads. Therefore, the stress fields have been generally one or two dimensional. Anti-roll bar is a component belongs to the suspension system of the vehicles. In spite of having simple circular section, due to the having several curvatures, this component experiences a three-dime...
متن کاملcyclic fatigue resistance and fractographic analysis of race and protaper rotary niti instruments
introduction: this study investigated the fatigue and fracture modes of race and protaper rotary instruments. materials & methods: fatigue resistance was evaluated by rotating the files 30 ° or 60 ° and with 2 or 5mm radius of curvature. race taper 06 size 25 and protaper f1 files (n=40) were used. the number of rotations to failure was analyzed by two-way anova and independent sample t-tes...
متن کاملCyclic fatigue behavior of nickel-titanium dental rotary files in clinical simulated root canals.
BACKGROUND/PURPOSE Dental rotary instruments can be applied in multiple conditions of canals, but unpredictable fatigue fracture may happen. This study evaluated the fatigue lives of two batches of nickel-titanium (NiTi) dental rotary files operating in clinically simulated root canals. METHODS Single-step cyclic fatigue tests were carried out to assess the performance of two batches of NiTi ...
متن کاملSafe way for using NiTi rotary files
In the clinical practice, it is much more efficient to use NiTi rotary files compared to hand instrumentation. However, misuse of NiTi rotary files can result in procedural errors such as transportation, ledge, perforation, and file separation. Generally, following suggestions could be considered to avoid these errors. 1. Enlarge the coronal half of the root canal before preparing the apical pa...
متن کاملCyclic Fatigue Resistance and Fractographic Analysis of Race and Protaper Rotary NiTi Instruments
INTRODUCTION This study investigated the fatigue and fracture modes of RaCe and ProTaper rotary instruments. MATERIALS AND METHODS Fatigue resistance was evaluated by rotating the files 30° or 60° and with 2 or 5mm radius of curvature. RaCe taper 06 size 25 and ProTaper F1 files (n=40) were used. The number of rotations to failure was analyzed by two-way ANOVA and independent sample t-test. F...
