title: The measurement and modelling of the mechanical properties of human skin in vivo--I. The measurement.
abstract: The mechanical properties of human skin in vivo are studied by means of uniaxial strain measurements. In order to obtain a stress-strain relationship which is independent of the in vivo measuring configuration, values for the effective width and effective length of the loaded skin strip have to be known. By variation of tab width and tab distance in a few series of experiments on the same subject, these effective values are found. In order to obtain a time independent stress-strain relationship a correction procedure is introduced. In this procedure the time dependent (viscoelastic) effects are described and subtracted from the total response.
