Tensile tests on heart specimens
Universal testing machine inspekt duo 10 kN with videoextesometer ONE1
Background and objectives
The mechanical properties of animal pericardial tissue are being investigated as part of a research project. The aim is to obtain comparative data for synthetic heart implants and to compare the elastic modulus of synthetic and natural heart tissue. As research results in this area are limited, the experiments provide valuable insights for the development and optimization of biological implant materials.
Test setup and implementation
For the tests, the inspekt duo 10 kN universal testing machine was used in combination with the video extensometer ONE1. The measurements were carried out on heart tissue from cattle and pigs using a 200 N load cell.
Particular attention was paid to:
- Differences in the elastic modulus with and without extensometer
- Evaluation of the forces for different specimen types
- Data for the design of a biaxial shear frame
Significance of the results
The data obtained enables a detailed analysis of the mechanical properties of cardiac tissue and serves as a basis for the further development of synthetic implants. By precisely measuring strain and force, targeted improvements can be achieved in the production of biological implant materials.
