A variational model of fracture for tearing brittle thin sheets [PDF]

open access: yes, 2018
Tearing of brittle thin elastic sheets, possibly adhered to a substrate, involves a rich interplay between nonlinear elasticity, geometry, adhesion, and fracture mechanics.

Early Detection of Damages Based on Comprehensive Theory of Deformation and Fracture [PDF]

open access: yesThe 18th International Conference on Experimental Mechanics, 2018
Numerical studies have been conducted based on the recently published Deformation Field Theory. Effects of pulling rates on displacement waves and volume expansion waves are analyzed in a finite element model (FEM) of a solid experiencing a uni-axial tensile load.

Pre-fatigue influence on quasi-static tensile properties of Ti-6Al-4V in thin-sheet form [PDF]

open access: yes, 2010
The response of engineering structures to loads is most often assessed without taking possible damage of the used material(s) into account. However, it has already been proved that a preceding cyclic loading and the alteration of the microstructure it ...

Fracture as a material sink

open access: yesMaterials Theory, 2017
Cracks are created by massive breakage of molecular or atomic bonds. The latter, in its turn, leads to the highly localized loss of material, which is the reason why even closed cracks are visible by a naked eye.

Energy Evolution and Damage Mechanism of Fractured Sandstone with Different Angles

open access: yesEnergies, 2022
To explore the influence of crack angle on the mechanical properties, energy evolution, and damage evolution of sandstone, uniaxial loading tests were conducted on sandstones with different crack angles.

A mesoscopic theory of damage and fracture in heterogeneous materials

open access: yesTheoretical and Applied Fracture Mechanics, 2004
Abstract Deformation patterns in solids are often characterized by self-similarity at the mesolevel. The framework for the mechanics of heterogeneous solids, deformable over fractal subsets, is briefly outlined. Mechanical quantities with noninteger physical dimensions are considered, i.e., the fractal stress [σ ∗ ] and the fractal strain

Ways of application of the provisions of mechanics of bodies with cracks to the calculation of asphalt concrete on strength and plasticity

open access: yesMATEC Web of Conferences, 2018
The report discusses the principles of two major theories of fracture mechanics of bodies with cracks, which include the theory of accumulation of damage Kachanov–Rabotnov and theory of brittle fracture Griffith–Irwin, including the invariant integral ...

Probability Analysis of Widespread Fatigue Damage in LY12-CZ Aluminum Alloy Single-Row Seven-Hole Plate

open access: yesAerospace, 2022
In order to determine the average behavior time of widespread fatigue damage (WFD) in an aircraft multi-site damage (MSD) structure and complete the fatigue analysis of WFD sensitive parts, this paper adopts a probabilistic method to analyze the crack ...

The Layout of the Combustion Cavity and the Fracture Evolution of the Overlying Rock during the Process of Underground Coal Gasification

open access: yesGeofluids, 2022
Based on the thermodynamic and elastodynamic theories, the controlling equation of temperature-stress coupling action on rocks containing random damage units is established by combining the Mogi-Coulomb damage criterion.
