- Abstract
- Over the past decades, the mechanical behavior of biological material has had
a profound effect on research into human tissues and the development of medical
devices. Studies from macrostructures to nanostructures of biological materials have
been investigated. Experimental tools have been used to explore these mechanical
properties. Soft material is one of the most widely found biological materials in
nature. Understanding the mechanical behavior of soft material is important in order
to develop cell mechanics and clinical devices. This thesis investigates the mechanical
behavior of polydimethylsiloxane (PDMS) under large deformation by conducting
deep indentation contact experiments. We use a long thin indenter to indent into three
different PDMS samples to explore their strain behaviors under large deformation.
We find the relationship between the loading force and the deformation of PDMS. A
hysteresis is also found between the loading process and the unloading process. Three
potential factors of viscoelasticity, friction and surface roughness are discussed.
