| Popis: | Biaxial tension is the usual type of stress on prosthesis parts made from polymer sheets. The chemical characteristics of medical elastomers in static and cyclic biaxial tension are poorer than in monaxial tension. These indices may be used for a realistic evaluation of the feasibility of using a given material for prostheses. Biaxial tension produced by a punch in conjunction with light transmission measurements may yield information on the production process and the condition of the material. Static and cyclic liquid pressure measurements are irreplaceable for medical elastomers and products, since they reveal the specific mechanisms for rupture, which may not be noted using other types of stressing. |
