Optimization of Stress-Relief Grooves for Rotary Shoulder Connections
IADC/SPE Drilling Conference, 2000Abstract Field experience and finite element studies have established the effectiveness of utilizing a stress relief groove on the pin of a threaded connection to prolong its life. Nevertheless, the exact design geometry of the stress relief groove is subject to discussion and even controversy. Moreover, the need to recut damaged threads

Parametric optimisation of stress relief groove shape in flat ends of boilers
The Journal of Strain Analysis for Engineering Design, 2011Flat ends of boilers with stress relief grooves have been used for many years. The existing standards set the value for the endplate thickness and admissible range of values for radius of the groove and the minimum thickness of the endplate under the relief groove.

Using stress relief grooves to reduce stress concentration on axle drive shaft
Journal of Mechanical Science and Technology, 2014The axle drive shaft has important roles such as transferring power and changing the steering angle between the axle and the wheel in a power train system. It is used in most heavy construction machinery, where a high degree of reliability is required in the power train system.

Actuation Enhancement of PZT Thin-Film Membrane Actuators via Stress Relief Grooves
Volume 4: 20th International Conference on Design Theory and Methodology; Second International Conference on Micro- and Nanosystems, 2008Lead Zirconate Titanate Oxide (PbZrxTi1−xO3 or PZT) is a piezoelectric material widely used as sensors and actuators. For microactuators, PZT often appears in the form of thin films to maintain proper aspect ratios. A common design is PZT membrane microactuator, whose actuation portion takes a form of a thin diaphragm driven by a PZT thin film.

Size optimization of shoulder filleted shafts with relief grooves for improving their fatigue life
AIP Conference Proceedings, 2020Stress concentration is defined as the localization of high stress due to irregularities present in the component or sudden change in cross section. Stress concentration deteriorates the life of the component, reduces mechanical properties and leads to material wastage. Full scale tests are time consuming and expensive.

An Investigation of Shaft Relief Grooves in Tailshaft Assemblies
Marine Technology and SNAME News, 1969Various relief grooves, located in the shafts between the liners and the hubs, were investigated with regard to their effects on the fatigue strengths of conventional tailshaft assemblies. It was found that tailshaft assemblies could be designed which would fail in the groove, regardless of whether single or increment loads were used, and that the ...

Teeth Clearance and Relief Grooves Effects in a Trochoidal-Gear Pump Using New Modules of GeroLAB
Journal of Mechanical Design, 2012As trochoidal-gear pump specifications become more demanding and design cycles shorter, the use of an innovative tool for modeling and simulation can be a cost effective and valuable guide to a more effective experimental work. The existing methodologies and software fail to thoroughly address the design by taking into account real effects to maximize ...
