押込試験による非弾性変形挙動の定量分析法の検討

抄録

An evaluation procedure of damage and fracture is introduced by using indentation technique in this paper. The damage and fracture are ordinary evaluated by tensile test, but it has difficulty to quantify them for soft material because of its large deformation. Then indentation technique is adopted as a material test for soft materials. The quantification procedure is depending on fundamental Hertzian contact theory, and it is extended for the evaluation. The extended theory is applied to the specimen of chicken, and the availability of the extended theory is discussed by the evaluated results of indentation test.
