A review of Finite Fracture Mechanics: crack initiation at singular and non-singular stress raisers
TL;DR: In this article, a coupled criterion was proposed for finite fracture mechanics, which is applied to different materials and structures: notched specimens, laminates, adhesive joints or embedded inclusions, and it is shown that this criterion gives predictions in agreement with experiments in various cases of stress concentration.

Optimal strength and toughness of Al2O3–ZrO2 laminates designed with external or internal compressive layers
TL;DR: In this article, two alumina-zirconia laminates with external (ECS-laminates) and internal (ICS-laminate) compressive stresses have been investigated using a fracture mechanics weight function analysis.
Journal ArticleDOI
On the relationship between ceramic strength and the requirements for mechanical design
TL;DR: In this article, the theory of brittle fracture and the underlying assumptions are critically discussed and the measurement procedures of strength are reviewed, and three main factors are identified which have to be considered much more than in the past: (i) hidden stresses caused by thermal strain mismatch, by contact (for example in joints) and internal stresses, (ii) the quality of the component's surfaces and edges and (iii) proper handling of ceramic materials and components.

Application of high resolution DLP stereolithography for fabrication of tricalcium phosphate scaffolds for bone regeneration.
Christina Schmidleithner,Sara Malferrari,Robert G. Palgrave,Daniel Bomze,Martin Schwentenwein,Deepak M. Kalaskar +5 more
TL;DR: To evaluate suitability of 3D scaffolds produced by DLP methods for bone regeneration, scaffolds were cultured with murine preosteoblastic MC3T3-E1 cells and retention of biocompatible and osteo-inductive properties of β-TCP following the DLP process is confirmed.

Al-Mg-Si/SiC laminated composites: Fabrication, architectural characteristics, toughness, damage tolerance, fracture mechanisms
TL;DR: Different architectures of layered laminates comprising two exterior layers of Al-Mg-Si/SiC metal matrix composite and an Al1050 ductile interlayer were fabricated by means of hot roll-bonding with applying different strains of er = 39, 51, and 63 as mentioned in this paper.

A Critical Evaluation of Indentation Techniques for Measuring Fracture Toughness: I, Direct Crack Measurements
TL;DR: In this paper, the application of indentation techniques to the evaluation of fracture toughness is examined critically, in two parts: the first part is focused on an approach which involves direct measurement of Vickers-produced radial cracks as a function of the indentation load.

An empirical stress-intensity factor equation for the surface crack
James C. Newman,Ivatury S. Raju +1 more
TL;DR: In this article, an empirical stress-intensity factor equation for a surface crack as a function of parametric angle, crack depth, crack length, plate thickness and plate width for tension and bending loads was presented.

Crack deflection at an interface between dissimilar elastic-materials
M.Y. He,John W. Hutchinson +1 more
TL;DR: In this paper, the authors examined the competition between deflection and penetration when the materials on either side of the interface are elastic and isotropic and determined the range of interface toughness relative to bulk material toughness which ensures that cracks will be deflected into the interface.
