Growth, Remodeling and Residual Stress in Soft Tissues

Biomechanics can be defined as the development and application of mechancis to
solve problems in biology. In the beginning the development of biomechanics went slowly, due to the
lack of knowledge of the needed mathematics.
In the beginning of 1980 laboratory work began to develop and more and more
realistic models begin to appear.
Most soft tissues include anisotropic,
compressible and add to that fiber reinforcement, smooth muscle
cells and the ability to remodel itself due to e.g., deseases, and growth,
and you have a very complex material. To be able to develop an adequate model for soft
tissues that include growth one must find a constitutive relation that describe the tissue
realisticly and an evolution law that describe the change of mass and geometry.
The goal for this research project is
to develop an adequate model that should be able to describe the complex
behavior of human arteries. The governing equations consist of parameters
unique for the material. One way to obtain these parameters are by solving a
curve-fitting problem. To solve this type of problems one need experimental
data. The model developed here use only data obtainable in vivo, that is data
measurable in living specimens.
