| Popis: | The skeletal system from mechanical point of view operates as supporting structure carrying forces and moments which occur during regular functioning of human body. The disturbances of these functions results in changing of mechanical characteristics of bones tissue so their evaluations could be a useful indicator of sickness and pathological conditions. The research of methods of mechanical characteristics of biological tissue should pay an attention to its strong anisotropy and sensitivity with respect to the conditions of the examination. A model of paradigm in biomechanics bones was described with its specifics and conditions. The theoretical description of the mechanics of bones deals with constitutive equations corresponding to the functional Wolff's adaptation theory. For proper estimation of strength the laws of crack propagation were applied. Some methods on mechanical and age-related characteristic, were described. As an example research on bone protection in the shoulder area against the results of side hitting (e.g. car accidents) was presented. This paper shows that bone mechanics study enables a better understanding of the relations between the mechanical properties of bones and the tendencies to illness and their changes with biological age. |
