Instron tensile
testing and imaging techniques for measuring suture displacement on chicken
skin during uniaxial tension
Name: Nikhil Bhargava
Class: BE 210
The experimental goals for this project include: determining whether the relative suture strength from prior experimentation holds for actual skin rather than cloth surrogates and determining which suture technique is the strongest for chicken skin. The hypothesis for the experiment is the pulley stitch is stronger, i.e. exhibits less deformation over the gap between skin pieces sutured together, than the running locked technique. This experiment’s objectives also extend those listed for the Suture Technique and Chicken Skin labs. These objectives include: quantifying displacement and strain, understanding the challenges of using image data acquisition for deformation analysis and understanding the challenges associated with testing biologic tissue samples and with the Instron Model 4444.
