Fracture mechanics by three-dimensional crack-tip synchrotron X-ray microscopy
To better understand the relationship between the nucleation and growth of defects and the local stresses and phase changes that cause them, we need both imaging and stress mapping. Here, we explore how this can be achieved by bringing together synchrotron X-ray diffraction and tomographic imaging. Conventionally, these are undertaken on separate synchrotron beamlines; however, instruments capa...
متن کاملSpecial issue on three-dimensional video and television
The term three-dimensional television (3DTV) is understood as a natural extension of two-dimensional television—which produces a flat image on a screen—into the third dimension. This means that the impression of the viewer also involves the perception of depth. Our two eyes view the world from slightly different positions and the two slightly different images registered by our eyes play a prima...
متن کاملPreface SPECIAL ISSUE ON BRAIN NEURO-MECHANICS
In July 2010, the Centre for Mathematical Medicine organized the first interdisciplinary workshop on Brain Neuro-Mechanics, under the patronage of the Fields Institute. The focus of the workshop was on recent discoveries in fundamental brain science that could play an important role in improved medical diagnoses, treatment strategies and clinical protocols. The workshop brought together experts...
متن کاملSome Remarks on Elastic Crack-tip Stress Fields
It is shown that if the displacement field and stress intensity factor are known as functions of crack length for any symmetrical load system acting on a linear elastic body in plane strain, then the stress intensity factor for any other symmetrical load system whatsoever on the same body may be directly determined. The result is closely related to Bueckner's [1] "weight function". through whic...
متن کاملSubmitted to Engineering Fracture Mechanics IMPROVED QUARTER-POINT CRACK TIP ELEMENT
We present a modi cation to the quarter-point crack tip element and employ this element in two-dimensional boundary integral fracture analysis. The standard singular element is adjusted so that the near-tip crack opening displacement satis es a known constraint: the coe cient of the term which is linear in the distance to the tip must vanish. Stress intensity factors calculated with the Displac...
