component of the stressâstrain behavior is associated with ï¬brillar slippage.21,22,24 The yield and failure re-gion (strains above 0.6 for skin) involves ï¬bril deï¬bril-lation.18 Results of viscoelastic tests conducted on human dermis from donors between the ages of 47 and 86 years suggest that the elastic spring constant of the
