Why Bones Break A bone breaks when the energy it is forced to absorb is stronger than the bone itself. This means that for the bone to break, at least one of three things likely occurred:1 Too much energy was applied to the bone all at once Too much energy was placed on the bone o...
Crack refers to a narrow break or fissure in a surface, often without material separation, while a fracture denotes a complete or partial break in a bone or solid material, usually involving separation.

These large values are due to dissipative mechanisms which add to the work, 2γs, required to break the atomic bonds. Cleavage initiated from intergranular carbides in mild steels In mild steels it is assumed that cleavage fracture initiates from very brittle platelets of cementite located along ...
Figure 12 shows through increasing slopes of the lines to points for various metals a graphical assessment of the temperature rise for sudden release of a dislocation pile-up avalanche when breakthrough occurs at the theoretical limiting microstructural stress intensity for cleavage (Armstrong and El...
DA is the finite change of the crack cross-section at the onset of fracture which can be derived from the fracture mode analysis; in the present case it corresponds to a single bond break at the crack-tip as seen in the mode. DFM accounts for the strain energy of discretized atomic ...
Moreover, the elongation at break and the impact strength of some HDPE-rich blends exceed those of pure HDPE polymer. This means that HDPE can be further toughened by brittle PS minor phase in the presence ofSEBS compatibilizer. It is noted that a high amount of SEBS (10 wt%) was ...
Acute hemorrhage occurs as soon as a vessel has ruptured. Hemosiderin is a break down product of heme and macrophages engulf the heme to remove it from the tissue. In severe trauma, the breakdown of erythrocytes takes a long time, during which hemosiderin-laden macrophages are present, and is...
An olecranon fracture is a break at the base of the elbow joint. Although an olecranon fracture can usually be treated by placing...
more common and have a higher impact on the health and quality of life of older women. Hip fractures often occur as a result of falls, and women are more prone to falls due to factors such as osteoporosis, which is more common in women and can cause bones to weaken and break ...
