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

Notch fracture toughness of glasses: Rate, age and geometry dependence [PDF]
, 2016 Understanding the fracture toughness (resistance) of glasses is a fundamental problem of prime theoretical and practical importance. Here we theoretically study its dependence on the loading rate, the age (history) of the glass and the notch radius $\rho$

An Extreme Toughening Mechanism for Soft Materials [PDF]
arXiv, 2022 Soft yet tough materials are ubiquitous in nature and everyday life. The ratio between fracture toughness and intrinsic fracture energy of a soft material defines its toughness enhancement. Soft materials' toughness enhancement has been long attributed to their bulk stress-stretch hysteresis induced by dissipation mechanisms such as Mullins effect and ...

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
