Journal ArticleDOI
Tightening characteristics for screwed joints in osseointegrated dental implants
Richard L. Burguete,Richard Johns,Richard Johns,Toby King,Toby King,Eann A. Patterson,Eann A. Patterson +6 more
TL;DR: The significance of tightening abutment screws and gold cylinders to osseointegrated fixtures with the correct torque is demonstrated, and a simple relationship between applied torque and screw preload is derived by use of mechanical engineering principles.
Journal ArticleDOI
Towards full field automated photoelastic analysis of complex components
Eann A. Patterson,Z F Wang +1 more
TL;DR: The design of a automated system for photoelastic analysis of complex components and the potential of the system for providing detailed data over the full field of view is demonstrated by the analysis of a slice from a model of a bolt.
Journal Article
Theoretical analysis of the fatigue life of fixture screws in osseointegrated dental implants.
Eann A. Patterson,Richard Johns +1 more
TL;DR: Metal fatigue failure of the gold screw used to retain a fixed prosthesis to Brånemark osseointegrated fixtures/abutments has been analyzed theoretically and mechanical engineering principles show the importance of appropriate preload being applied through the gold Screw to the gold cylinder and abutment.
Journal ArticleDOI
A review of the general theory of thermoelastic stress analysis
TL;DR: In this paper, a complete and detailed insight into the origins of the various forms of the equations describing the thermoelastic effect is given with reference to the concepts of the thermodynamic theory of a continuum.
Journal ArticleDOI
Measuring stress intensity factors during fatigue crack growth using thermoelasticity
TL;DR: In this article, the results of fatigue crack growth tests performed on welded ferritic steel plates are reported, and it can be observed that the technique is sensitive to the effects of crack closure and the presence of tensile and compressive residual stresses due to welding.
