Overview
Rheology is the study of the flow and deformation of matter. In it, we relate stresses and strains for nearly all materials that we encounter in daily life, including biomaterials and biomedical devices. In this talk we will discuss applications of rheology fundamentals to testing biomaterials and biomedical devices. We will discuss the 2 main approaches to rheological testing – unidirectional testing, such as flow testing on fluids and transient tests on solid-like materials, as well as dynamic oscillatory testing. For dynamic oscillatory testing, we will describe the different test modes: dynamic stress and strain sweeps, frequency sweeps, time sweeps, temperature ramps, and temperature/frequency sweeps, and will show the useful information that rheological testing can provide. We will also describe some accessories that pertain to testing of biomaterials.
