The effects of notch root radius on fracture toughness and crack initiation sites have been investigated in this paper using three different classes of materials. Data on alumina which represent ceramics, mild steel from the metals family and polycarbonate representing plastics were obtained and analysed. The locations of crack initiation sites have been pinpointed by scanning electron microscopy. These identified sites more or less are located within the critical process zone or the… 
Metals: Brittle Fracture in Metallic Materials
This chapter focuses on brittle fractures in metallic metals. A brittle fracture is any fracture that occurs by the rapid and unstable extension of a crack. In metals, crack growth can occur by one

An improved Finite Fracture Mechanics approach to blunt V-notch brittle fracture mechanics: Experimental verification on ceramic, metallic, and plastic materials
Abstract The coupled Finite Fracture Mechanics (FFM) criterion is applied to investigate brittle fracture in rounded V-notched samples under mode I loading. The approach is based on the
Understanding the failure of epoxy resin U-notched samples using cohesive models
Abstract The critical distances theory for predicting failure loads of notched solid polymers requires assuming very high values of the characteristic stress. These values have to be much higher than
Predicting the fracture strength of ceramic materials using the theory of critical distances
This paper describes a critical distance theory which uses local stress field information to predict the effect of stress concentrations. The approach was originally developed for predicting fatigue
Fracture of notched samples in epoxy resin: Experiments and cohesive model
Abstract The prediction of failure loads in notched samples has been one of the most motivating fracture mechanics issues for a long time. Most efforts have been focused on the application of
Analysis of fracture data from notched specimens can provide information on multiscale toughening mechanisms
Abstract The identification and quantification of toughening mechanisms in materials is a difficult task which is often made more difficult by the presence of several mechanisms operating at
Brittle failure criteria for components containing U-notches under Mode I loading
Abstract In this study, a modified fracture criterion which satisfies the necessary stress and energy conditions is proposed for brittle materials. The criterion is based on the assumption that
Critical crack-healing condition for SiC whisker reinforced alumina under stress
Abstract Alumina reinforced by SiC whisker, called here “alumina(w)” was developed with the objective of improving fracture toughness and crack-healing ability. The composites were crack-healed at
Can the theory of critical distances predict the failure of shape memory alloys?
TLDR
It is shown here for the first time that these failures can be predicted using the theory of critical distances (TCDs), a method which has previously been used to study fracture and fatigue in other materials.
