Recently published data for fracture in human humeral cortical bone are analyzed using cohesive-zone models to deal with the nonlinear processes of material failure. Such models represent the nonlinear deformation processes involved in fracture by cohesive tractions exerted by the failing material along a fracture process zone, rather than attributing all damage to a process occurring at a sing...

The translaminar fracture toughness of laminated composites can be determined experimentally assuming either linear elastic mechanics (LEFM) or cohesive zone model (CZM) hypotheses. Each theoretical frame is different in terms complexity and predictive capabilities. To clarify the latter point, we derived R(Δa) J(ω) curves from a set published results on over-height compact tension specimens si...

Environment-assisted cracking (EAC) is one of the most serious causes of structural failure over a broad range of industrial applications including offshore structures. In EAC condition there is not a definite relation such as Paris equation in Linear Elastic Fracture Mechanics (LEFM). According to studying and searching a lot what the researchers said either a material has contact with hydroge...

Cohesive-zone models for interfaces incorporate both strength and energy parameters. Therefore, they provide a natural bridge between strength-based models and energy-based models for fracture, allowing delamination to be described by a single framework that covers a range of applications for which the strength or energy criteria alone might not be sufficient. In this paper, the relationships b...

In fracture mechanics and failure analysis, cracked media energy and consequently stress intensity factors (SIFs) play a crucial and significant role. Based on linear elastic fracture mechanics (LEFM), the SIFs and energy of cracked media may be estimated. This study presents the novel modification of decoupled scaled boundary finite element method (DSBFEM) to model cracked media. In this metho...

The concrete always contains microstructures like micro-crack, voids, etc. These parameters affected the lifetime of materials. This article presents a computation algorithm to predict brittle materials which depends on distribution micro-crack in proposed model is based subcritical crack growth using linear elastic fracture mechanics (LEFM) approach. considers both tensile and shear fracturing...

Abstract In peridynamic models for fracture, the dissipated fracture energy is regularized over a non-local region denoted as horizon. This paper investigates influence of this parameter on dynamic process in brittle solids, using two well three dimensional simulations propagation notched plate loading cases. The predicted crack speed various scenarios initially stored energy, also known veloci...

The rupture of the interface joining two materials under frictional contact controls their macroscopic sliding. Interface dynamics depend markedly on mechanical properties bulk that bound interface. When are similar, recent experimental and theoretical work has shown shear cracks described by Linear Elastic Fracture Mechanics (LEFM) quantitatively describe interfaces. elastic dissimilar, many n...

This paper presents a probabilistic assessment model for linear elastic fracture mechanics (LEFM). The model allows the determination of the failure probability of a structure subjected to fatigue loading. The distributions of the random variables for civil engineering structures are provided, and the relative importance of these random variables is determined. An example of a bridge detail is ...

• Geometrical nonlinearities cause deviations from LEFM even in materials with linear elastic response prior to cleavage Fracture is a collective phenomenon at the atomic scale, purely local and interactions toughness cannot be re-conciliated using only separation distance of crack tip atom pair an incremental loading procedure also influence lattice trapping Realistic nonlinear responses are a...
