Title:
力学特性試験方法
Document Type and Number:
Japanese Patent JP6856229
Kind Code:
B2
Abstract:
A test method for characterizing the mechanical properties includi ng the surface adhesion energyγon the basis of the experimentally de rived P-A relationship,where P means the indentation load under the penetration depth h of an indenter pressed onto a test specimen with surface adhesion, andA means the contact area of indentation at the contact radius a under the applied load of P.This test method enables the implementation for quantitatively as well as simultaneously characterizing the adhesion energy as well as the various mechanical properties (elastic/elastoplastic/viscoelastic properties) of soft materials.
