Description

technical field

[0001] The invention relates to the technical field of mechanical property testing. Specifically, the invention relates to a teaching experiment equipment for testing the mechanical properties of biological strip materials and a method for testing the mechanical properties of biological strip materials. Background technique

[0002] The mechanical properties of biological tissue materials, such as: hair, silk, spider silk, muscle, blood vessels, etc., are of great significance for the study of the normal and pathological states of organisms. The comprehensive mechanical properties of biomaterials can be obtained through uniaxial tensile testing, such as: stress-strain curve, breaking strength, breaking energy, relaxation curve and creep curve, etc.

[0003] In traditional physics experiment teaching, the experiment of measuring the Young's modulus of metal wire by stretching method is a classic experiment for measuring the elastic modulus of metal wire. In t...
