Changes in the three-dimensional microscale topography of human skin with aging impact its mechanical and tribological behavior
Fig 5
Effect of dermal thickness and stiffness on the mechanical response to indentation.
Contours of the Green Lagrange strain components E33 and E13 for the two oldest microrelief geometries for the reduced thickness model with dry SC condition, and for three values of the shear modulus for the dermis (a). Components E33 and E13 of the Green Lagrange strain plotted across the skin thickness in three different positions underneath the indenter (b).
