There are various methods to perform bending tests on biological tissues. The most common methods include:
1. Three-Point Bending Test: In this method, the tissue sample is placed on two supports, and a force is applied at the midpoint. This setup helps in measuring the material's flexural strength. 2. Four-Point Bending Test: Similar to the three-point bending test, but here the force is applied at two points. This method helps in reducing the shear stress and provides a more accurate measurement of the material's bending strength. 3. Cantilever Bending Test: In this test, one end of the tissue sample is fixed, and a load is applied at the other end. This setup is useful for measuring the elasticity of the tissue.
