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 ...

Low Force Fracture of the Odontoid, with Discussion of High Force Cervical Fracture
Academic Forensic Pathology, 2012Cervical fracture may occur with a high force mechanism of injury such as a motor vehicle crash, or with a low force mechanism of injury such as a ground level fall. To better characterize and understand low force cervical fractures and their significance, case files from the Travis County Medical Examiner's office covering a 5-year time period were ...

Dynamic fracture mechanics under electromagnetic force
Fusion Engineering and Design, 1988This paper is concerned with two topics on dynamic fracture phenomena related to electromagnetic force. An edge-cracked specimen which carries a transient electric current I is simply supported in a steady magnetic field B. As a result of their interaction, the dynamic electromagnetic force occurs in the whole body of the specimen, which is then ...

Force measurement on fracture site with external fixation
Medical & Biological Engineering & Computing, 1997A force measurement device has been designed to monitor the mechanical properties of fracture site with external fixation. Forces are measured through electric resistance strain gauges mounted on fixation framework and the measurement results are displayed on an LCD screen.

Relationship between applied force, deformation of egg shells and fracture force
Journal of Agricultural Engineering Research, 1967When an egg is compressed between flat parallel surfaces so that the compression surfaces contact the poles, the egg fractures most frequently at the large pole. However, the location of the moving surface may affect this frequency. In compression at the equator the moving surface has no effect.

Effect of Columbic Force on Piezoelectric Fracture
Key Engineering Materials, 2004This paper studies the effect of the Columbic force on piezoelectric fracture. Bound charges emerge on the upper and lower surfaces of a permeable crack when a piezoelectric solid with the crack is subjected to far-field mechanical/electric loading.

Possible role of dispersion forces in fracture
Philosophical Magazine, 2005Dispersion (London) forces act between any two solid bodies. These forces are small except when the bodies are close together. They decrease rapidly as the distance between the bodies increases. Near the tip of a crack one body separates into two, and the two pieces are close together for a short distance. Thus, dispersion forces may play a role in the

Perimortem fracture pattern in ribs by blunt force trauma
International Journal of Legal Medicine, 2018Literature on timing of rib trauma is scarce but remains challenging during forensic cases. This study analysed the macroscopic fracture patterns of perimortem rib fractures and compared them to experimentally reproduced rib fractures on fresh and dry ribs.

Control of fracture reduction robot using force/torque measurement
2008 30th Annual International Conference of the IEEE Engineering in Medicine and Biology Society, 2008We have developed a surgical robotic system for femoral fracture reduction employing indirect traction. Indirect traction in fracture reduction is a generally used surgical method for preventing complications such as bone splits caused by high stress on bones. For traction, a patient's foot is gripped by a jig and pulled to the distal side.
