The Forced Creep Analysis of Nonmetallic Material

Nonmetallic material by stress which less the yield stresses long time, it would force creep. Nonmetallic materials’ operating life depended on the creep degree. The paper set up creep model using ANSYS, create the nonmetallic material creep strain-time curve, got the creep properties of nonmetallic material. To provide effective basis of calculate the nonmetal materials’ operating life.

The intervertebral joints I: The intervertebral disc

The structure of the intervertebral disc is described in detail, some reference being made to clinically relevant aspects of the anatomy. Some biomechanical terms, such as motion and force, creep and hysteresis, are explained and discussed in relation to the intervertebral disc as a clinically important structure.
