摘要:
Force‐deformation curves are measured for individual human red blood cells by applying an equal and opposite force at diametrically opposite “points” on the red cell rim. Upon release of a cell, it rapidly recovers its unstressed disklike shape in approximately 0.3 sec. This deformation and subsequent recovery process is analyzed with a constitutive equation which describes the finite deformation at constant area of a two‐dimensional viscoelastic solid. From the analysis and the experimental results, values obtained for the “shear modulus of surface elasticity” and “coefficient of surface viscosity” are on the order of4×10−3 dyn/cmand5×10−4 dyn sec/cm(P cm), respectively.
