23 Jul Device and method for testing puncture resistance of soft material
Abstract
The invention discloses a device and a method for testing puncture resistance of a soft material, and belongs to the technical field of material performance testing. The puncture resistance of a flexible soft material as gel, rubber, muscle, skin, cartilage and hydrogel biomimetic material and the like in the puncturing process is difficult to scientifically and quantitatively measure at the present stage. According to the method, the puncture resistance when a needle body punctures the soft material is tested according to the momentum theorem, and the puncture resistance includes the membraneresistance of a puncturing needle head and the friction resistance between the puncture needle body and the soft tissue. The test technology is simple in principle, easy to operate and high in test precision, can effectively reflect the puncture behavior characteristics of the tested material, and has potential application value in the fields of flexible and soft material and biological tissue engineering.
