Vibrated concrete vs. self-compacting concrete: comparison of fracture mechanics properties [PDF]
, 2014 This study focuses on the fracture mechanics aspect of self-compacting concrete, compared to vibrated concrete. The most commonly used experiments to investigate the toughness and cracking behaviour of concrete are the three-point bending test (3PBT) on ...

Fracture Toughness of Tooth Acrylic
Key Engineering Materials, 1996 The hardness, fracture toughness, toughness, flexural strength and Young's moduli of three acrylic tooth polymers were investigated. The first polymer was based on a conventional homopolymer poly(methylmethacrylate). The second was based on cross-linked poly(methylmethacrylate) with an uncross-linked poly(methylmethacrylate) coating. The third material

Study of Thickness Effect on Fracture Toughness of High Grade Pipeline Steel
MATEC Web of Conferences, 2016 The critical fracture toughness decreases when thickness of specimens increases and stress-strain field in crack tip start changing to plane strain state from plane stress state. In this paper, fracture toughness tests were carried. Based on the analysis

Buoyancy-driven crack propagation: the limit of large fracture toughness [PDF]
, 2007 We study steady vertical propagation of a crack filled with buoyant viscous fluid through an elastic solid with large effective fracture toughness. For a crack fed by a constant flux Q, a non-dimensional fracture toughness K=Kc/(3μQm3/2)1/4 describes the
