Abstract Abstract: This paper studied experimentally and
theoretically the biomechanical properties of skin with laser
influence. Different types of tensile tests of the porcine skin in vitro
were conducted to study effect of the laser, tensile strength,
stress-strain relationship, influence of skin's anisotropy and
different regions, repetitive loading and stress-relaxation. A
modeling of skin was developed according to the experimental
results. The modeling provided insights into the important
structure-function relationship in skin tissue with the laser
effect. The nonlinear and anisotropic mechanical responses of skin
are largely due to varying degree of fiber undulation which is
effected by laser and outside forces. By introducing the laser
factor into the constitutive modeling, the skin's biomechanical
properties and the mechanism of the skin repair with laser were
discussed.
