Stress analysis in the Biological system is an engineering discipline that determines the stress related structures subjected dynamic changes due to internal or external stress producing factors. This discipline has now been entered into the study of different type of stressby computational modeling of related changes and dynamics that offers excellent exposure of the various components of a particular functional external or internal organ.The biggest advantage of this kind of computational modeling is the complete anatomic exposure, which allows the surgeon to inspect the tissue, muscle and bones framework. For example, in a recent study scientists have numerically quantified the stress induced on the scar of a human columella by a constant load, through a fine tuned finite elasticity continuum model in biological systems.
The columellar portion of the nose, with various constituting muscles and tissues, has been modeled in a first approximation as a hyperelastic body and different types of scars have been identified and considered for study of biological system.The above proposed computational simulation model can be applied both to theoretically designed and numerically verified new non-conventional scar geometries.
Numerical criteria for evaluating stress on such type of computational simulation models have applications in evaluating medical strategies, enabling better surgery training and the development of better medical techniques and tools. New software tools based on the numerical analytical model can be developed to calculate the stress dynamics, and geometrical simulation.
