Shading affects fracture force and fracture strain of apple fruit skins
Scientia Horticulturae, 2020Abstract Simple observation shows that naturally shaded apple fruit are more prone to russeting than sun-exposed fruit. The formation of microcracks in the fruit skin is the first visible sign of russeting. Our objective was to establish the effects of different levels of shading on the mechanical properties of apple (Malus × domestica Borkh.) fruit ...

Fracture mechanism of amorphous polymers at strain fields
Phys. Chem. Chem. Phys., 2014Owing to the wide application of polymeric materials, understanding the fracture mechanism of amorphous polymers at strain fields is a fundamentally important challenge. In this work, we use molecular dynamics simulations to investigate the uniaxial deformation of amorphous polyethylene and further monitor the polyethylene fracture process induced by ...

STRESS AND STRAIN ACTIVATED FRACTURE ELEMENTS2
Journal of Texture Studies, 1983The characteristics of fracture elements in which the activation criterion is either a critical stress and/or strain are described. Their possible effects on the properties of phenomenological rheological models are demonstrated in the case of simplified models subjected to hypothetical deformation, stress relaxation and creep tests.

Fracture Initiation in Plane Strain Forging
1985This paper presents a preliminary investigation of the ability of elastic-plastic finite-element simulations to predict the initiation of ductile fracture in bodies undergoing large plastic deformation.

Fracture mechanics applied to engineering problems-strain energy density fracture criterion
Engineering Fracture Mechanics, 1974Abstract Traditional design criteria make no attempt to account for the failure mode which is characteristic of a flawed, frangible structure. A design rationale is outlined for materials which contain flaws caused, for example, by metallurgical inclusions, fabrication and erection overloads, and fatigue cracking.

Fault-fracture strain in Wingate Sandstone
Journal of Structural Geology, 1989Abstract The Laramide deformation of the Triassic Wingate Sandstone along the northeast flank of the Uncompahgre uplift has occurred by faulting at various scales. Macroscopically smooth flexures of beds within the Wingate occur by small displacements across a myriad of intraformational, mesoscale faults.

Geological faults: fracture, creep and strain
Philosophical Transactions of the Royal Society of London. Series A, Mathematical and Physical Sciences, 1978To extend our understanding of faulting in the Earth’s crust it will be necessary to describe the various physical processes of faulting in terms of boundary and initial value problems. This is not easy to do. Field evidence indicates that faults form geometrically complex systems and time histories depend on the highly nonlinear processes

Fracture cleavage and strain-slip cleavage
1982Fracture cleavage and strain-slip cleavage are both non-pervasive cleavages, i.e. the individual cleavage planes are separated by uncleaved slices of rock termed microlithons. Nevertheless, they appear differently in the field and beneath the microscope; the microlithons associated with fracture cleavage are not folded, those associated with strain ...
