Simulation of Lumbar Spine Biomechanics Using Abaqus

Biomechanics testing of the lumbar spine, using cadaveric specimens, has the advantage of using actual tissue, but has several disadvantages including variability between specimens and difficultly acquiring measures such as disc pressure, bone strain, and facet joint contact pressure. A simulation model addresses all of these disadvantages. The objective of this work is to develop a method to s...

In-vitro mobility of the lumbar spine.

As part of a systematic study of the spine between D11 and S1 the response to stress has been assessed by measuring radiologically the total and segmental mobility of 103 specimens. The method was shown to be reproducible to within 10% of total mobility. No significant sex difference was seen. Total mobility varied widely, but mean total mobility fell with age. All lumbar segments became less m...

the effect of taftan pozzolan on the compressive strength of concrete in the environmental conditions of oman sea (chabahar port)

cement is an essential ingredient in the concrete buildings. for production of cement considerable amount of fossil fuel and electrical energy is consumed. on the other hand for generating one tone of portland cement, nearly one ton of carbon dioxide is released. it shows that 7 percent of the total released carbon dioxide in the world relates to the cement industry. considering ecological issu...
