Fracture Properties of Chicken Skin and Sutured
Chicken Skin
Name: Deana
Sin
Class: BE 210
It is hypothesized that unbroken (whole) chicken skin samples will have similar material properties as sutured skin samples. Thus, these properties (failure displacements, failure strains, and elastic modulus) as obtained by the INSTRON 4444 and LabView Software, will show no significant difference when compared with a t-test. Beyond simply testing this hypothesis, aims of this experiment also include appropriate allocation of supplies and correct interpretation and use of INSTRON data. The force-deformation plot given by the LabView software in combination with the appropriate measurements will be used to create a stress-strain plot in order to determine Young’s moduli and failure properties. The limited number of samples and amount of time requires experimenters to properly plan ahead in order to gather all the correct information. Experimenters will become familiar with real time data acquisition and the challenges associated with it. Meanwhile, hands-on experience will be gained with the difficulties of controlled preparation and testing of biological samples and use of the INSTRON 4444. Also, like in Experiment 2, this lab will yield practice with suturing techniques but with biological samples and real suturing materials.
