Biaxial flexural strength distribution of thin ceramic substrates with surface defects

The Effect of Core Material, Veneering Porcelain, and Fabrication Technique on the Biaxial Flexural Strength and Weibull Analysis of Selected Dental Ceramics

“…Because of the higher opacity of alumina‐based ceramic and zirconia‐based ceramic core material, they are required to be veneered with feldspathic porcelain to achieve an esthetic result. On the other hand, for the glass‐ceramic materials (lithium‐disilicate glass ceramic, leucite‐reinforced glass ceramic), they can achieve desirable esthetic restorations with veneering porcelain or by custom staining and glazing because of their high translucency 43 . Although the mechanical characteristics of the core materials have continuously been improved in modern dentistry, veneering material mechanical properties have largely remained unchanged 10 .…”

Dynamic Ring‐on‐Ring Equibiaxial Flexural Strength of Borosilicate Glass

“…Because dynamic loading may induce resonance in the sample that superimposes inertia forces on the intrinsic material response, there is an upper limit in the loading rates. The highest frequency component in the loading pulse should be controlled to be lower than the first resonant frequency of the specimen 13 …”

Experimental investigation of the biaxial strength of thermal barrier coating system

“…Cheng et al [16] proposed a statistical model for the strength of ceramic material based on Weibull distribution function. It is assumed that the present fracture strength σ b of the ceramic top-coat in TBCs obeys Weibull cumulative probability distribution function,…”

“…In the past decade, different test assemblies were developed to measure the bi-axial strength of brittle materials [12,13]. The most widely accepted one is the piston-on-three-ball test [13][14][15][16], in which the thin disc specimen is supported by three same balls near its periphery and the supporting balls are placed symmetrically to the center of disc, as shown in Fig. 1.…”
