Post-failure behaviour of impulsively loaded circular plates
(PERGAMON-ELSEVIER SCIENCE LTD, 2010)
The dynamic plastic response of a simply supported circular plate is analysed. Emphasis is given to the plate behaviour after it has broken free from the supports due to a local material failure. The theoretical rigid ...
Influence of the resin cement thickness on the fatigue failure loads of CAD/CAM feldspathic crowns
(Elsevier B.V., 2015-08-01)
Objectives, to evaluate the influence of the occlusal resin cement thickness on the cyclic loads-to-failure of feldspathic crowns and to compare the results to data from monotonic tests. A large range of cement thickness ...
The random barrier-crossing problem
(ELSEVIER SCI LTD, 2008)
This paper addresses the time-variant reliability analysis of structures with random resistance or random system parameters. It deals with the problem of a random load process crossing a random barrier level. The implications ...
Influence of convergence angle of tooth preparation on the fracture resistance of Y-TZP-based all-ceramic restorations
(2013-03-01)
Objective: To investigate the influence of the convergence angle of tooth preparation on the fracture load of Y-TZP-based ceramic (YZ-Vita YZ) substructure (SB) veneered with a feldspathic porcelain (VM9-Vita VM9). Methods: ...
Distortional buckling of simple lipped channel in bending results of the experimental analysis versus direct strength methods
(2006-12-01)
Cold-formed steel members are subject to failure caused by buckling, normally under loads smaller than those corresponding to partial or total yielding of the cross section. The buckling of members in bending can be ...
Effects of cement thickness and bonding on the failure loads of CAD/CAM ceramic crowns: Multi-physics FEA modeling and monotonic testing
(Elsevier B.V., 2012-08-01)
Objective. To determine the influence of cement thickness and ceramic/cement bonding on stresses and failure of CAD/CAM crowns, using both multi-physics finite element analysis and monotonic testing.Methods. Axially symmetric ...
Crown fracture: Failure load, stress distribution, and fractographic analysis
(Elsevier B.V., 2015-09-01)
Statement of problem. The outcomes from load-to-failure tests may not be applicable to clinical situations. Purpose. The purpose of this study was to critically evaluate the efficacy of load-to-failure tests in the ...
Fatigue failure load of two resin-bonded zirconia-reinforced lithium silicate glass-ceramics: Effect of ceramic thickness
(2018-06-01)
Objectives: To evaluate the effect of ceramic thickness on the fatigue failure load of two zirconia-reinforced lithium silicate (ZLS) glass-ceramics, adhesively cemented to a dentin analogue material. Methods: Disc-shaped ...
