1. Objectives

• To determine the two sample’s unique ability to withstand tensile forces by observing ultimate strength data.
• To determine the relative elasticity of both adhesion methods through observing average failure displacement.
• Ultimately, the tensile and elastic properties of the two adhesive methods will depict the unique adhesion applications of the two methods. For example, sometimes elasticity is more important that ability to withstand forces (perhaps if wound is located at site of little load application).

2. Hypothesis

• Under the load application, the skin samples with Steri-StripTM will have a significantly higher ultimate strength than the samples with a suture technique.

The skin samples with double sided stitching will have a significantly higher average failure displacement.
